The Argo Hytos SP2A-A3 Pressure Reducing-Relieving Valve is a spool-type, direct-acting valve designed to regulate pressure in hydraulic systems. It lowers the pressure to a set level below the supply pressure, ensuring stable operation even with varying flow rates. Additionally, it acts as a relief valve during shock or surge pressures, redirecting excessive pressure and flow to the tank to protect the system from damage. With features like excellent stability, rapid response to pressure changes, low hysteresis, and accurate pressure control, this valve offers reliable performance. It has a wide range of input pressure capabilities and is adjustable using an allen key or hand screw. The valve is zinc-coated for added protection against corrosion.
