Assembly

7 ASSEMBLY

DANGER!

Risk of injury from high pressure in the system.

▶Before loosening lines or valves, turn off the pressure and vent

the lines.

Preparatory work

→Observe flow direction (see type label).

→Clean pipelines (sealing material, swarf, etc.).

Devices with welded body

Remove the actuator from the valve body:

→Clamp the valve body into a holding fixture.

NOTE!

Damage to the seat seal or the seat contour!

→Open the valve for control functions A and I: Pressurize the

lower pilot air port with compressed air (5 bar).

→Place a suitable open-end wrench on the wrench flat of the nipple.

→Unscrew the actuator off the valve body.

Devices with threaded body:

→Only disassemble the actuator if required by the customer.

7.1 Installation

WARNING!

Risk of injury from improper installation!

Damaged parts or incorrect tightening torques can cause leaks on

the equipment.

▶Use an open-end wrench for the assembly.

▶Observe the tightening torque (see torque table).

Devices with approval in accordance with DIN EN 161

In accordance with DIN EN 161 "Automatic Shut-off Valves for Gas

Burners and Gas Appliances", a strainer must be installed upstream

of the valve to prevent a 1 mm test pin from penetrating.

7.1.1 Installing the body

Welded body:

→Weld valve body in pipeline system.

Other body designs:

→Connect body to pipeline.

7.1.2 Installing the actuator (welded body)

→Check graphite seal and, if required, replace. Fully remove any

residue when replacing the seal.

WARNING!

Danger due to lubricants that contaminate the medium!

In oxygen applications there is a risk of an explosion!

▶Only use approved lubricants for specific applications, such as

oxygen or analytical applications.

english

Type 2000

Assembly

→Lubricate the nipple thread before reinstalling the actuator

(e.g. with Klüberpaste UH1 96-402 produced by Klüber).

Graphite seal

NOTE!

Damage to the seat seal or the seat contour!

→Open the valve for control functions A and I: Pressurize the

lower pilot air port with compressed air (5 bar).

→Observe the tightening torque when screwing the actuator into

the valve body (see table).

Orifice (DN) 15 20 25 32-40 50-65

Tightening torque ± 3 [Nm] 45 50 60 65 70

7.2 Rotating the actuator

The actuator can be rotated infinitely by 360°.

→Clamp the valve body into a holding fixture (if necessary).

NOTE!

Damage to the seat seal or the seat contour!

→Open the valve for control functions A and I: Pressurize the

lower pilot air port with compressed air (5 bar).

→Using a suitable open-end wrench, counter the wrench flat on

the nipple.

→Place a suitable open-end wrench on the hexagonal bolt of the

actuator.

WARNING!

Risk of injury from discharge of medium and release of pressure!

If the direction of rotation is wrong, the body interface may become

detached.

▶Turn the actuator in a clockwise direction (as seen from above).

7.3 Connecting the control medium

DANGER!

Risk of injury from high pressure in the system!

▶Turn off the pressure and vent the lines before loosening lines or

valves.

WARNING!

Risk of injury from unsuitable hoses!

▶Use only hoses which are authorized for the indicated pressure

and temperature range.

▶Observe the data sheet specifications from the hose

manufacturers.

The actuator can be rotated infinitely by 360°. See section

“7.2 Rotating the actuator”.

8 START-UP

▶Observe the type label specifications and information on

pressure and temperature values in section “6 Technical

data”.

8.1 Control pressure

WARNING!

For control function I – Danger if control pressure fails!

If the pressure fails, no defined position is reached.

▶For a controlled restart, initially pressurize the equipment with

control pressure and then connect the medium.

→Set the control pressure according to the type label specifica-

tions (section “6”) and flow direction (section “8.2” and “8.3”).

8.2 Flow above the seat

Control function A, CFA: closes by spring force with the medium flow.

The medium pressure supports the closure and seal of the valve seat.

The valve is opened by the control pressure.

WARNING!

Risk of injury due to water hammer!

A closing shock can cause lines and the equipment to burst.

▶Only use valves with the flow above the seat for gaseous media.

To ensure complete opening, the minimum control pressure

must be used!

Type 2000

Disassembly

8.3 Flow below the seat

Control function A, CFA: closes by spring force against the medium flow.

Control function B, CFB: closes with the control pressure against the

medium flow. The medium pressure supports the opening of the valve.

CFA/CFI CFB/CFI

Flow below the seat (closing

CFA

WARNING!

Seat leaks caused by the minimum control pressure being too

low (on CFB and CFI) or the medium pressure being too high!

▶Observe the minimum control pressure and medium pressure

(see “6.6.1 Pressure ranges”).

8.4 Maintenance work

→Complete a visual inspection of the equipment once a year. Shorter

maintenance intervals may be recommended depending on the

operating conditions.

Wear parts: seals and swivel plate.

→In the event of a leak, replace the relevant wear part.

The maintenance and repair instructions are available on the

Internet: www.burkert.com

9 DISASSEMBLY

DANGER!

Risk of injury from discharge of medium and pressure!

It is dangerous to remove a device which is under pressure due to

the sudden release of pressure or discharge of medium.

▶Before removing a device, switch off the pressure and vent the lines.

Procedure:

→Loosen pneumatic connection.

→Remove device.

10 TRANSPORTATION, STORAGE,

DISPOSAL

NOTE!

Transport and storage damage!

▶Protect the device against moisture and dirt in shock-resistant

packaging during transportation and storage.

▶Permitted storage temperature: -20 – +65°C.

Damage to the environment caused by device components

contaminated with media.
