Direct Acting Differential Area Relief Valves

*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.

Parker's selection of differential area relief valves provide excellent pressure control in applications where a fast acting, low leakage relief valves are needed with operating pressures up to 380 bar (5500 psi) and flows up to 151 lpm (40 gpm) through a wide selectin of cartridge sizes. Unlike the direct acting family of relief valves, Parker's differential area relief valves are designed to have the pressure controlled at port 2 of the cavity. This ensures low leakage across the valve, essential in some holding applications. Designed using industry common cavities, Parker’s line of differential area reliefs can easily be used in various mobile and industrial system applications.
