Differential Relief Valve in Manifold with Manometer Port
Differential relief cartridge in a zinc plated steel manifold body with an integral 1/4" BSPP gauge port — allowing a pressure gauge or transducer to be connected directly at the relief valve without additional fittings. Available in 3/4" and 1" BSPP port sizes, it is rated to 400 bar and 160 l/min.
The gauge port makes the RVDD-M-160 particularly useful during commissioning, fault-finding, and performance verification of high-pressure circuits.
