10.2 Installing the valve
If there is tension, the actuators may jam.
If the actuators jam, it may no longer be possible to reposition them.
• During installation, make sure that the valve is fitted in the pipeline without any strain.
• Compensate for thermal expansion of the pipeline with expansion joints.
1. Suspend the valve separately and align it as required. Observe the direction of flow (see markings on the
valve and in Fig. 1 – Fig. 7).
2. Protect valves from dirt.
3. Remove the protective caps.
4. Check the inside of the valve and the pipeline and, if necessary, clean them to remove any foreign parti-
cles.
5. Centre the seals between the connecting flanges. The connecting flanges must be aligned.
6. Tighten the flange screw connections. Observe the tightening torques (See “Tightening torques” on
page 10).
10.3 Connecting the valve electrically
Risk of crushing due to moving actuators!
Reaching into the device can lead to fatal injury from crushed and severed limbs.
• Only connect and operate the valve when it is correctly installed.
Danger of electric shock!
Live conductors pose a hazard when working on the valve.
• Before working on the valve, de-energise the electrical control line and secure it against being switched
on again.
1. Connect the valve to the electrical control system as described in the manufacturer’s documentation (See
“Other applicable information” on page 4).
11 Commissioning
Risk of fatal injury due to leaking piping system and missing protective devices!
Operating an incorrectly or incompletely installed piping system can lead to life-threatening injuries due to
escaping media.
• Ensure that all work on the piping system has been completed.
• Ensure that all protective devices are intact and correctly fitted.
• Ensure that the piping system is free of contamination.
1. Perform a leakage test.
12 Decommissioning
1. Depressurise the piping system.
2. Allow the medium in the piping system to cool down.
3. Drain the system.
4. Ventilate the piping system if media with one of the following properties are used:
• Corrosive
• Flammable
• Aggressive
•Toxic
5. Switch off the solenoid drive (800).
