Unloader Relief Valves

Raptor Supplies offers a huge variety of unloader relief valves from brands like Dayton, AR North America and Pulsafeeder to protect low-volume / high-pressure pumps from pressures above 3000 psi. These relief valves feature nylon / stainless-steel / brass / bronze / PVDF construction to handle a maximum flow rating of 40 gpm. Selected models are also designed to apply a positive discharge pressure to prevent backsiphoning and eliminate varying dosage rates caused by fluctuating downstream pressure.
