The Ashford Instrumentation Ltd Coplanar 5-valve direct mount manifold from our Generation 200 Series is manufactured from 316 stainless steel (other materials also available)  and valve features 54mm instrument centres and primarily used on differential pressure transmitters. .

Compact design, direct block mounted five-valve manifold, instrument mount to pipe connection. This valve offers two isolation valves, two vent valves and one equalising valve. This manifold features bubble tight shut off, 2-piece non-rotating hardened tips and unique bonnet locking cam.

Please note that this 5-valve manifold can be supplied with the vent valves on the side or on the bottom. Please see drawings attached for preferred design.

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.
