REPLACING THE VALVE SET

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.

WARNING!

Risk of injury if the wrong tools are used!

It is dangerous to use unsuitable tools for installation work as the device may be damaged.

• To remove the actuator from the valve body, use an open-end wrench, never a pipe wrench.

Before the valve set can be replaced, the actuator must be removed from the valve body.

Remove the actuator from the valve body:

→ Clamp the valve body in a holding device

(applies only to valves which have not yet been installed).

english

Replacing valve set:

→ Support swivel plate on the cylindrical part with the aid of a prism

or something similar.

→ Knock out the pin with a suitable pin punch.

Pin punch ø 3 mm, for spindle diameter 10 mm on the swivel plate (see “Tab. 1”). Pin punch ø 5 mm, for spindle diameter 14 mm on the swivel plate (see “Tab. 1”).

→ Remove swivel plate.

→ Connect new swivel plate to the spindle. → Align bores of the swivel plate and spindle. → Support swivel plate on the cylindrical part with the aid of a prism

or something similar.

→ Insert pin into the bore. → Swage pin bores on both sides of the swivel plate using a chisel

or center punch.

Installing the actuator on the valve body:

→ Check the graphite seal and if required, replace it.

WARNING!

Danger if incorrect lubricants used!

Unsuitable lubricant may contaminate the medium. In oxygen applications there is a risk of an explosion!

• In specific applications, e.g. oxygen or analysis applications, use appropriately authorised lubricants only.

→ Grease nipple thread before re-installing the actuator (e.g. with

Klüber paste UH1 96-402 from Klüber).

NOTE!

Damage to the seat seal or the seat contour!

• When installing the actuator, ensure that the valve is in open position.

→ Control function A pressurize the pilot air port 1 with compressed

air (5 bar): valve opens.

→ Screw actuator into the valve body.

Observe tightening torque (see “Tab. 2”).

WARNING!

Risk of injury from parts jumping out!

When the spindle opening is exposed, the individual parts of the packing gland are pressed out at an undefined speed when the pilot air ports is pressurized.

• Before pressurizing with control air, safeguard the ambient area of the discharge opening (e.g. place spindle on a firm base).

→ Control function A and I Pressurize pilot air port 1 with 6 – 8 bar. → Control function B Pressurize pilot air port 2 with 6 – 8 bar. → Grease the individual parts of the new packing gland with the

upplied lubricant.

→ Connect the individual parts to the spindle in the specified

direction and sequence.

→ Push packing gland into the packing gland tube. → Screw spindle guide back in using the installation tool. Observe

torque (see “Tab. 3”)!
