Critical System Protection

  • Prevents Catastrophic Overload – As the main system relief valve, it sets the maximum pressure limit for the entire hydraulic circuit. When system pressure exceeds the preset limit, the valve opens instantly to relieve excess pressure, protecting expensive components such as pumps, control valves, and cylinders from damage.
  • Fast & Accurate Response – The relief valve provides overload protection in a fast and accurate way: when it reaches the pressure setting, the valve opens immediately to prevent pressure from exceeding the safe limit.

Precision Engineering & Durability

  • Hardened Internal Components – Featuring internal parts made of hardened and ground steel for excellent wear resistance and long service life under high-pressure conditions.
