A cartridge-style pilot-operated poppet -type relief valve with reverse free flow check

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.Pressure at ② overcomes the spring-bias pressure 2 ～ 3bar and allows free flow from ② to ①，then in its steady state, pressure maintains at 1.4 bar.
