Installation

Risk of personal injury due to preloaded 

springs.

Actuators with preloaded springs are under 
tension. They can be identified by the long 
bolts protruding from the bottom of the actu-

ator.

 

Î

Before starting any work on the actuator, 
relieve the compression from the pre-
loaded springs (see associated actuator 
documentation).

To test the valve functioning before start-up 

or putting back the valve into operation, per

-

form the following tests:

5.4.1 

Leak test

The plant operator is responsible for per

-

forming the leak test and selecting the test 
method. The leak test must comply with the 
requirements of the national and internation

-

al standards that apply at the site of installa

-

tion.

Our after-sales service can support you to 
plan and perform a leak test for your plant.

1. 

Close the valve.

2.  Slowly apply the test medium to the inlet 

space upstream of the valve. A sudden 
surge in pressure and resulting high flow 

velocities can damage the valve.

3.  Open the valve.

4. 

Apply the required test pressure.

5.  Check the valve for leakage to the atmo-

sphere.

6.  Depressurize the pipeline section and 

valve.

7. 

Rework any parts that leak (see informa

-

tion below under ‘Adjusting the packing’) 

and repeat the leak test.

Adjusting the packing

A label on the yoke indicates whether an ad-
justable packing is installed (see the 'Mark-

ings on the device' section).

Risk of valve damage due to the use of 

unsuitable tools.

 

Î

A special tool is required for form HT 
packings (

u

 AB 0100).

Impaired valve functioning due to increased 

friction as a result of the threaded bushing 

being tightened too far.

 

Î

Make sure that the plug stem can still 
move smoothly after the threaded bush-
ing has been tightened.

1.  Tighten the threaded bushing gradually 

(by turning it clockwise) until the packing 
seals the valve.

2. 

Open and close the valve several times.

3.  Check the valve for leakage to the atmo-

sphere.

4.  Repeat steps 1 and 2 until the packing 

completely seals the valve.
