1 INTRODUCTION

1.1 General

The NP700 positioner is used for positioning double or sin-

gle acting actuator.

1.2 Principle of operation

Operation is based on the force balance principle. One force

is caused by the signal pressure (IN) and acts on the dia-

phragm (8), and the other is the compression force caused

by the feedback spring (60.1). The latter is directly propor-

tional to the position of the lower end of the spring, which

is in turn dependent solely on the position of the actuator

shaft via the lever (33), the cam (29), the positioner shaft

(26) and the coupling (52).

When the equilibrium between the forces mentioned

above is disrupted, the beam (5) moves in the direction of

the stronger force. The end of the beam moves the spool

(44.2) in the bore of the body (44.1). When diverted from

the equilibrium position, the spool guides the supply air to

one side of the actuator piston and the air on the other side

of the piston outside.

When the spool is in the equilibrium position the small vol-

ume of leakage past the spool creates an equal pressure on

either side of the unloaded cylinder piston. This pressure is

roughly 0,7 x the supply pressure.

If the signal pressure is altered, the spool moven out of the

equilibrium position and causes a pressure difference in the

cylinder. The piston moves in the direction of the difference

pressure until the compression force of the feedback spring

generated by the change in position is in equilibrium with

the force generated by the signal pressure.

Thus each signal pressure value corresponds to a single

actuator position. If an external force acts on the actuator

shaft, the shaft tends to move in the direction of the torque.

This alters the position of the spool via the feedback system

so that the pressure difference arising in the cylinder offsets

the effect of the external torque.

material. Most parts have material marking. A material list is

supplied with the positioner. In addition, separate recycling

and disposal instructions are available from the manufac-

turer. A positioner can also be returned to the manufacturer

for recycling and disposal against a fee.

1.7 Safety precautions

2 MOUNTING ON THE METSO ACTUATOR

2.1 General

When the positioner is supplied together with the valve and

actuator, the tubes are mounted and the positioner adjusted in

accordance with the customer's specifications.

When the positioner is ordered separately, the mounting parts

for the assembly must be ordered at the same time.

Example order: Positioner alone (BC12)-Z-NP724.

The positioner is equipped with VDI/VDE 3845 (S1) mount-

ing face.

This mounting face requires a shaft with the H coupling.

Old Metso Automation mounting face (S2) is no more avail-

able.

For mounting parts for Metso actuators, see Sections

13.2–13.3.

CAUTION:

Do not exceed the positioner performance limitations!

Exceeding the limitations marked on the positioner may

cause damage to the posioner, actuator and valve.

Damage or personal injury may result.

CAUTION:

Do not dismantle a pressurized positioner!

Dismantling a pressurized positioner will result in uncon-

trolled pressure release. Always isolate the relevant part of

the pipeline, release the pressure from the positioner and

the piping.

Failure to do this may result in damage or personal injury.

CAUTION:

Beware of the moving parts when positioner is oper-

ated!

2.2 Installing positioner NP700/S1 on

Metso actuators with VDI/VDE 3845

mounting face

1. The actuator piston must be in the up position (in spring-

return actuators as determined by the spring).

2. Install the pointer (only B_U) parallel with the valve clo-

sure member and fasten the draught piece (2) with a

screw (29) to the pointer cover (B_U) or to the coupling

(QP), as shown in Fig. 4. Secure the draught piece fasten-

ing screw with a sealant (e.g. Loctite) and tighten it

properly.

3. Fasten the mounting bracket (1) to the positioner.

4. Fasten the mounting bracket (1) to the actuator.

2.3 NP_700/700 positioner/limit switch

combination (Obsolete since 2013)

The bottom of the limit switch acts also as the cover for the

positioner. Remove the limit switch before the adjustment

of the positioner.

1. Loosen the cover screws. Note the position of the shaft

relative to the positioner when removing the limit switch.

2. When the adjustment of the positioner is done, operate

the actuator until the valve is in the closed or open posi-

tion.

3. Note the position of the actuator and valve when

mounting the limit switch on the actuator. Make sure

that the position of the shaft is unchanged relative to

the positioner.

4. Place the limit switch on the positioner so that the

shafts are correctly engaged.

5. Fasten the cover screws.

6. Check the adjustment of the limit switch. See the

instruction manual of the limit switch for details.

2.4 Piping of supply air

Table 2 provides the recommended pilot valve and tube

sizes in accordance with the actuator sizes. Tube sizes are

minimum values allowed.

Connect air supply to S (1/4 NPT).

Connect C1 and C2 (1/4 NPT) to the actuator according to

Fig. 5. See also Chapter 3.

Connect signal air to IN (1/4 NPT).

For pipe threads are liquid sealants, e.g. Loctite, recom-

mended.

2.5 Instrument air supply

The supply air must be clean, dry and oil-free instrument air,

e.g. according to standard ISA S7.3-81. Supply pressure is

1.4–10 bar (20–140 psi).

Fig. 4 Installing on a Metso actuator (S1)

NOTE:

A single action connection alone is permitted for position-

ers mounted on the spring actuator!

Place a plug in connection C1 or C2. See Figure 5.

NOTE:

Exessive sealant may cause faulty operation of the posi-

tioner.

Sealing tape is not recommended.

Ensure the cleaness of the air piping.

CAUTION:

Do not exceed the permitted actuator supply air pres-

sure!

3 INPUT SIGNAL AND DIRECTIONS OF

OPERATION

Figure 6 assists in choosing the right segment for the cam

plate (29) and position for the changeover piece (46).

3.1 Changeover piece

The function of connection C1 and C2 can be altered by

turning the changeover piece (46). The diagram D (or R)

shown on the protective plate (48) functions when the sym-

bol D (or R) is visible in the lower lefthand corner of the

changeover piece (46).

D = direct, R = reverse.

External changes in the tubes are not needed. Positioner

NP727 is an exception (DIA6HC pilot valve). Then the

changeover piece must always be in position R and the

external tubes mounted in accordance with Fig. 5.

3.2 Cam plate

The figures marked on the cam plate (29) are the signal

ranges expressed as percentages, for example 0-100 corre-

sponds to 0.2–1.0 bar (3-15 psi), or 50-100 to 0.60-1.0 bar (9-

15 psi), see Fig. 6.

The arrows on the cam show the direction it must turn

when the input signal is rising in the cam segment in ques-

tion.

The non-rising segments between the rising segments are

roughly 15-20°.

4 PRELIMINARY ACTIONS FOR THE

ADJUSTMENT

Set the valve’s open and closed limits with the actuator lim-

iter screws; see the valve instruction manual. The changeo-

ver piece (46) and the cam (29) must be in correct positions.

Check the pilot valve size from Table 2.

The adjustment must always be carried out when the sup-

ply pressure has been changed.

Please note that operating of the valve is required during

the adjustment.

4.1 Position of the changeover piece

Choose the position of the changeover piece, D or R, from

Fig. 7 in accordance with the function desired.

Turn the changeover piece (46) when necessary.

Loosen the nuts (49) and remove the protective plate (48).

Pull out the changeover piece (46). Check the O-rings (47, 2

pcs.) and apply silicone grease lightly if needed. Place the

changeover piece (46) and the protective plate (48) in the

case. Tighten the nuts (49) evenly, one after the other.

4.2 Pilot valve

Removal of the pilot valve is unnecessary when the change-

over piece is turned around. For instructions of removal, see

Section 8.2.

4.3 Position of the cam plate

Choose the side, A or B, and the rising segment of the cam

plate from Fig. 7 in accordance with the function desired.

Move the actuator piston to the end where the input signal

has its lower value. Shut off the supply pressure or move the

pilot spool by deflecting the beam (5) gently so that the pis-

ton strokes to the desired limit. The input signal should be

zero or at the lower limit.

7 NP 72 en 9

Loosen the screw (57), remove the indicator (32), loosen the

screw (31) and the locking wheel (30). Turn the cam plate

(46) to the desired side.

In case of α0adjustment proceed acc. to Sections 6.1 and

6.2.

Place the roller so that its contact point is 1 mm (0.04") from

the beginning of the rising segment. Then tighten the lock-

ing wheel (30) and the screw (31).

5 BASIC ADJUSTMENT

Basic adjustment is made to rotary and butterfly valves.

Please note the procedures in Chapter 4 before the adjust-

ment.

1. Switch on the supply pressure (S) and the input signal

(IN).

2. Set the input signal at the closed limit of the valve so

that it is 2 % i.e. 0.02 bar (0.2 psi) higher or lower than

the limit value, e.g. 0.2 + 0.02 = 0.22 bar (3 + 0.2 = 3.2 psi)

or 1.0 - 0.02 = 0.98 bar (15 - 0.2 = 14.8 psi). Loosen the

screw (56). Turn the zero adjustment screw (67) so that

the actuator comes slowly to the closed limit. Tighten

the screw (56) always after the zero adjustment. The

valve should open slightly with a 4 % change in signal,

that is 0.03 bar (0.5 psi), e.g. 0.2 + 0.03 = 0.23 bar (3 + 0.5

= 3.5 psi) or 1.0 - 0.03 = 0.97 bar (15 - 0.5 = 14.5 psi). See

Figures 8 and 9.

3. Set the input signal to the other limit value. The valve

should be entirely open at 100 %, i.e. 1.0 bar (15 psi) or

0.2 bar (3 psi). The valve should start to operate to

closed direction at 98 %, i.e. 0.98 bar (14.0 psi) or 0.22

bar (3.2 psi). The range, i.e. turning angle, changes when

the effective lenght of the spring (60) is increased or

decreased by turning the range adjustment nut (60.3).

See Fig. 9.

4. The zero and range adjustments affect each other, so

stages 2 and 3 must be repeated a few times.

5. Screw on the pointer (32) into place so that the yellow

line is in the direction of the valve closing member.

Tighten the screw (57).

6α0ADJUSTMENT

α0adjustment is made to segment and ball valves. This

adjustment takes into account the "dead angle" α0of the

ball valve. The entire signal range is then used for effective

The same adjustment method can be applied to butterfly

valves in papermills for pulp flow control to avoid the dewa-

tering of the pulp near the closed position of the disc.

Table 3 shows the shift on the circumference of the cam

equal to the "dead angle" of the valve, Figure 11, in various

cam segments (C, E, D).

Please note the procedures in Chapter 4 before the adjust-

ment.

1. Mark the shift in question on the edge of the cam, Fig. 11

and Table 3. Dimensions do not have to be measured if

the dead angle can be reliably noticed from position of

the closing member.

2. Lock the cam so that the roller touches the edge of the

3. Switch on the supply pressure (S) and the input signal

(IN).

4. Set the input signal at the closed limit of the valve so

that it is 2 % i.e. 0.02 bar (0.2 psi) higher or lower than

the limit value, e.g. 0.2 + 0.02 = 0.22 bar (3 + 0.2 = 3.2 psi)

or 1.0 - 0.02 = 0.98 bar (15 - 0.2 = 14.8 psi). Loosen the

screw (56). Turn the zero adjustment screw (67) so that

the actuator comes slowly to the closed limit. Tighten

the screw (56) always after the zero adjustment. The

valve should open slightly with a 4 % change in signal,

that is 0.03 bar (0.5 psi), e.g. 0.2 + 0.03 = 0.23 bar (3 + 0.5

= 3.5 psi) or 1.0 - 0.03 = 0.97 bar (15 - 0.5 = 14.5 psi). See

Figure 9.

5. Set the input signal to the other limit value. The valve

should be entirely open at 100 %, i.e. 1.0 bar (15 psi) or

0.2 bar (3 psi). The valve should start to operate to

closed direction at 98 %, i.e. 0.98 bar (14.0 psi) or 0.22

bar (3.2 psi).

The range, i.e. turning angle, changes when the effective

lenght of the spring (60) is increased or decreased by turn-

ing the range adjustment nut (60.3). See Fig. 9.

6. The zero and range adjustments affect each other, so

stages 4 and 5 must be repeated a few times.

7. Screw on the pointer (32) into place so that the yellow

line is in the direction of the valve closing member.

Tighten the screw (57).

7 SPLIT-RANGE ADJUSTMENT

In principle, split range adjustments are made in the same

manner as for a normal signal range. Select a split range,

20-60 kPag / 0.2–0.6 barg / 3–9 psig or 60-100 kPag /

0.6–1.0 barn / 9–15 psig, from the cam plate. See Figure 6.

8 MAINTENANCE

Regular maintenance is not necessary.

The need for maintenance depends on the quality of the

instrument air. See also Section 2.5.

If there is need for servicing proceed according to the fol-

lowing sections.

8.1 Supply air filter

The supply air filter (50) is located in the supply air connec-

tion (S); the filter can be removed for cleaning.

8.2 Pilot valve

Remove the pilot valve (44) by first loosening the nuts (49),

and then by lifting off the protective plate (48), the change-

over piece (46) and the gasket (45).
