 Key attributes

Critical System Overload Protection
  The primary function of this relief valve is to act as a safety guard for the hydraulic system. By limiting the maximum pressure in the swing circuit, it provides fast and accurate overload protection. When system pressure reaches its preset limit, the valve opens to release excess hydraulic fluid, preventing damage to the swing motor, pump, and other expensive components. This ensures your excavator operates within safe pressure limits, significantly reducing the risk of catastrophic failures and costly downtime.

Reliable & Durable Construction
  Engineered to withstand the demanding conditions of heavy excavator use, this valve is built with zinc-plated steel for excellent corrosion resistance. Its hardened and ground steel internal parts provide exceptional wear resistance and long service life. The poppet-type, direct-acting cartridge design is both dirt-tolerant and fast-acting, making it ideal for demanding service line protection.
