1. General Terms

This instruction manual should be read carefully by the competent

operating and maintenance personnel.

We point out that we will not accept any liability for damage or

malfunctions resulting from the non-compliance with this instruction

manual.

Descriptions and data given herein are subject to technical

changes.

2. Safety Instructions

The valves must be assembled, disassembled and reassembled

only by persons who have been trained in the valves or by SPX

FLOW service team members. If necessary, contact your local SPX

FLOW representative.

Caution!

The technical safety symbol draws your attention to important

directions for operating safety. You will nd it wherever the activities

described are bearing health hazards and risks for persons and / or

material assets.

-Do not reach into the open valve ball or yoke.

Risk of injury by sudden valve operation!

In dismantled valve state, there is the risk of bruising at movable

valve parts.

- During valve operation, operating leakage spurts out to the bottom.

- If the cleaning connection is not used, it must be sealed by a plug or

operating leakage must be discharged.

- Regular maintenance of the valve including replacement of all seals

must be scheduled in order to prevent leakage and liquid emersion.

- Remove the turning actuator before the replacement of seals.

- Before any maintenance work, the line and cleaning system must

be depressurized and discharged if possible.

- Separate electric and pneumatic connections.

- Observe service instructions to ensure safe maintenance of the

valve.

2. Safety Instructions

-Caution!

Welded actuators are preloaded by spring force.

Actuators which are no longer used and/or are defective must be

disposed in professional manner.

Defective actuators must be returned to your SPX FLOW company

for their professional disposal and free of charge for you.

Please address to your local SPX FLOW company.

Opening of the turning actuators is strictly forbidden.

Danger to health and life!

The intended use as eld of application of the double seat ball

valve is the shut-off of pipeline sections.

Arbitrary, structural changes at the valves may affect safety as well

as the intended functionality of the valves and are not permitted.

4. Mode of Operation

4.1. Gerneral

Due to the use of high-quality stainless steel and seal materials

complying with the specified requirements, the double seat

ball valve DELTA DKR2 is applicable in the food and beverage

industries as well as in the chemical and pharmaceutical industries.

The field of application of the DELTA DKR2 valve comprises the

separation of two line sections with different fluids (B and C) by two

independent seals with intermediate leakage chamber and free

drain (D) to the atmosphere.

Actuation by the pneumatic turning actuator with air connection at

(A), reset into the limit position "closed" by spring force.

- The free opening cross section has the same dimension as the

nominal diameter of the pipeline.

- Smooth valve passage without diversion of the fluid.

- Cleaning of the leakage chamber by supply of cleaning liquids via

the cleaning connection (E).

- During the operating process, operating leakages drain off from the

leakage drain (D). If a cleaning line is not connected, the cleaning

connection (E) must be sealed by a plug or operating leakages

draining from (E) must be discharged.

- The cleaning nozzle (E) can be used to flush the leakage chamber

with water, or with CIP liquids and clean it with water, for fast

emptying, to vent or to sterilize the leakage chamber with steam.

- DKRX special valves are available, for example for highly viscous

products with extended leakage drain or for horizontal installation.

5. Auxiliary Equipment

5.1. Valve position indication

Switches to signal the limit position of the valve ball can be installed

in the yoke area if requested.

We recommend using APV standard proximity switches.

Type: three-wire proximity switch (ref.-No. 08-60-011/93; H16223)

Operating distance: 5 mm / diameter : 11 mm / length: 30 mm

Feedback complete with support and proximity switch

(ref.-No. 15-33-023/33; H32725) for a limit position.

If the customer decides to use valve position indicators other than

those listed above, SPX FLOW cannot assume any liability for the

functionality of the valve.

5.2. Control unit (CU, fig. 5.2.)

Units with feedback switches and solenoid valves for the pneumatic

control of the valve to be assembled on the actuator are also

available in eldbus technology.

The assembly of the control unit on the prepared variant of the

turning actuator is possible.

For the startup as well as assembly and disassembly of the different

designs, the corresponding operating manuals must be observed.
