Detail

The pressure relief valve of HYDAC DB3E-02-C-V-250V220 is a direct-acting, spring-loaded poppet valve. Its function is to relieve pressure in the system. The spring exerts a force on the poppet and presses it on the valve seat. On the opposite side, the system pressure exerts force on port 1 of the valve.

If the HYDAC hydraulic pressure is below the pre-set spring tension, the valve is closed. Only if the hydraulic force exceeds the preset spring tension does the valve open and flow is diverted to tank via port 2.

Important: Pressures at port 2 are additive to the opening pressure. If the connections are incorrect or if the pressure has been set above the operating pressure, the effect of the valve is disabled.
