  • Technical Feature

    OPERATION:

    The valve prevents flow from ① to ② until pressure at ① exceeds the set Cracking Pressure and opens the pilot section. The pilot flow creates a pressure differential across the poppet which causes the valve to open allowing flow from ① to ② protecting the circuit from over pressurization.If the pressure at ② is at least 2 bar higher than Pressure at ① . The main poppet will be lifted out of its seat, to allow flow from ② to ①, this feed function is used to make up for lacking hydraulic fluid volumes.

    Pressure at port ③ is directly additive to the valve setting at a 1:1 ratio and should not exceed 50bar.
