The Argo Hytos SR1A-A2 Pressure Relieving Valve is a direct-acting hydraulic relief valve designed as a screw-in cartridge for easy integration into hydraulic systems. It functions as a pressure limiting device, safeguarding the hydraulic circuit from overpressure situations. This poppet-type valve operates by utilizing a spring to press the poppet onto the valve seat. When the hydraulic pressure exceeds the pre-set value, the valve opens, allowing flow to pass to the tank port until the pressure falls back below the set value. With features such as excellent stability, rapid response to pressure changes, low hysteresis, and accurate pressure control, this valve ensures reliable performance and system protection. Additionally, its hardened precision parts and dirt-tolerant steel seats contribute to long-lasting durability and leak-free operation. The valve is adjustable using an allen key or hand screw and comes standard with zinc coating for corrosion protection.
