BRV1
Bi-directional Relief Valve
OPERATION
The value is a direct-acting, dual cross-over relief valve in a single cartridge format. When pressure at either port exceeds the nominal setting value, flow will be transmitted to the opposite port. Back pressure at either port will affect the nominal setting of the opposite port on a 1:1 basis.
For correlation purposes,pre-set value will be measured at port 2.
Pressure at port 1 will not exceed ± 150 psi from the port 2 value.
