Product Overview
The Parker R4S06 535 11 A1 is a pilot operated sequence valve from Parker Hannifin’s R4S series of pressure control valves. It is designed to control the sequence of operation of two or more hydraulic actuators by opening a secondary circuit only after a predetermined pressure has been reached in the primary circuit. The valve operates on a balanced piston, pilot operated principle, providing smooth and accurate pressure control with minimal pressure override. Its robust construction and precise adjustment mechanism make it suitable for demanding industrial hydraulic systems requiring reliable, repeatable sequencing of machine functions.
