Pilot-Operated Sequence Valve with Reverse Check

Brand: Parker Hannifin

Parker’s pilot operated sequence valve with a built-in reverse check reduces manifold space, complexity, and the number of components in a hydraulic system. 

These valves can work with pressures up to 420 bar (6000 psi) and flows up to 70 lpm (18.5 gpm) and allow for multiple double acting functions to be operated with a single directional control valve. 

Parker’s pilot operated sequence valve with a built-in reverse check can be utilized in several applications, but is ideal for load control and clamping or press applications within mobile and industrial markets.
