These instruments are recommended for use with clean, dry,
oil free instrument grade air to BS 6739 or ISA-7.0.01-1996
Dew Point: At least 10°C (18°F) below anticipated ambient temperature.
Dust: Filtered to below 5 microns
Oil Content: Not to exceed 1ppm mass.
The inlet and outlet ports are threaded G1/4 or 1/4”NPT female
and suitable fitting should be used. For most installations
1/4” (6mm) pipe will be adequate. Always ensure that the
downstream volume between the output of the VP50 and
the actuator/device is between 100cc and 2000cc.
If the air supply is not of adequate quality this can normally
be achieved by the use of an air filter regulator. In all cases,
purge the supply pipework before connection to the valve.
The use of a soft setting anaerobic seal is recommended,
(e.g. Loctite Hydraulic Seal 542). Always follow the sealent
manufacturer’s recommendations during use.
Under no circumstances should PTFE tape be used for sealing
the fittings as this tends to shred small particles which may
contaminate the instrument and cause malfunctions.
