Manual-Test

6.Installation

Examine valve for in-transit damage, damaged sample valves must not be installed.

  • Before installation the valve and the connecting pipe must be carefully cleaned to remove any dirt, especially hard foreign matter.
  • During installation, pay attention to the correct tightening torque, aligned pipes and tension-free assembly.

6.1 Flange caps and gaskets

Leave protective caps on the flanges until just prior to installation.

Where there is a particularly high risk of damage to the plastic sealing surfaces, e.g. if the mating flanges are made of metal or enamel, PTFE-lined gaskets with a metal inlay should be used. Contact the Manufacturer for further discussion.

6.2 Direction of flow and installation position

The direction of flow must be observed when installing the valve. It is indicated by a direction arrow on the valve body.

6.3 Grounding

The valve must be grounded. This can be achieved in the simplest way via the pipe screws using tooth lock washers. One pipe screw per flange is underlaid with toothed disks.

Upon customer request a set screw M6 is attached to each flange with a hex nut and washer as an additional earthing connection.

Otherwise grounding must be ensured by different measures e.g. a cable link

6.4 Test pressure

The test pressure PT of a valve must not exceed the value of 1.5 x PS(PN) as per the identification of the valve.
