Start-up

6.1 Start-up and putting the

device back into operation

1. Depending on the field of application,

allow the regulator to cool down or

warm up to reach ambient temperature

before start up.

2. Slowly open the shut-off valves in the

pipeline. Slowly opening these valves

prevents a sudden surge in pressure and

high flow velocities which can damage

the valve.

3. Check the regulator to ensure it functions

properly.

6-2

1. Start up the regulator after mounting all

parts.

2. Open the shut-off valves slowly prefera-

bly starting from the upstream pressure

side. Afterwards, open all the valves on

the consumer side (downstream of the

regulator).

3. Fill the plant slowly with the process me-

dium. Avoid pressure surges.

4. Make sure that the pressure rises simulta-

neously upstream and downstream of the

regulator to avoid damaging it.
