Direct acting relief valves have a simple design and rigid static response characteristics, which significantly depend on the pressure and flow rate of the liquid. They have sufficient speed due to the small mass of moving parts. The stability of the static characteristic of valves is negatively affected by frictional forces and the non-linearity of the characteristic of a long spring. Therefore, direct operated relief valves are periodically adjusted during operation.

Features of Pressure Relief Valves

Direct acting pressure reducing valves, presented in the Metkoff Ltd. catalog, are capable of delivering flow rates up to 120 liters per minute and withstanding a maximum pressure of 250 Bar.

This’s a safe certified equipment, the quality of which meets international standards. Its use will ensure long-term and stable functioning of hydraulic systems.
