1CEH90 Overcenter Valve - Pilot assisted relief with check

1CEH90 - High pressure overcenter valve

Pilot assisted relief with check 1CEH90: 90 L/min (23 USgpm) • 350 bar (5000 psi)

Operation

The check section allows The check section allows free flow into the actuator then holds and locks the load against movement. The pilot assisted relief valve section will give controlled movement when pilot pressure is applied. The relief section is normally set to open at a pressure at least 1.3 times the maximum load induced pressure but the pressure required to open the valve and allow movement depends on the pilot ratio of the valve. For optimization of load control and energy usage, a choice of pilot ratios is available.
