5-Valve Manifold Remote Mount Angled Bonnet Pipe To Pipe - Model AIR5 Generation 200 Series

The Ashford Instrumentation Ltd 5-Valve Manifold Remote Mound Angled Bonnet Pipe To Pipe from our Generation 200 Series is specially designed for a wide range of applications including differential pressure transmitters.

Operation: In normal operation the isolate valves are open while the vent valve and plug are closed. This provides a differential pressure reading to the pressure gauge or transmitter. To zero the instrument, first close both vent valves and the downstream isolate valve. Then open the equalise valve and adjust the zero setting on the instrument. To remove the instrument, first close both isolate valves, then open the equalise valves to relieve pressure between the manifold and the instrument. 

Instrument Calibration:  An option provided by 5-valve manifolds which is not available on 3-valve types is connecting the vent port to known pressure sources to check the calibration of the instrument.


As well as supplying process valves, Ashford Instrumentation Ltd can also supply an extensive range of pressure gauges and pressure transmitters.
