5.7 Iso-Sense pilot operated pressure relief
valve
In this special pilot operated pressure relief
valve, the sense pressure applied to the pilot
inlet/sense port is supplied from a remote
source and the sense pressure media is
isolated from the process media. The valve
assembly is available for either a gas or
liquid process media with either a gas or
liquid sense media. The typical Iso-Sense
pilot operated pressure relief valve shown in
Figure 13 below is presented for identification
purposes only. This is a special pressure relief
valve assembly which may require special set
pressure adjustment procedures. Contact
Anderson Greenwood for replacement parts
and maintenance instructions for individual
valve assemblies (serial number is required for
complete identification).
