Sequence valves provide ordered sequencing of two or more operations as with clamp and drill circuits. They can also be used as relief valves where the down-stream pressure is high or changes during operation. By taking the drain line directly to tank, back pressure effects are negated.

As in the case of Poppet Relief valves, when the inlet pressure at Pressure Port (1) exceeds the valve setting, the poppet lifts off the seat and the Pressure Port (1) is opened to the Sequenced Port (2) allowing for the sequenced flow to take place. Flow coming back from Port 2 is allowed to flow directly to Port 1 via the check seat.

Hardened, match ground and honed working parts give long, trouble-free life. There is a consistent and stable operation providing a low pressure override even with increasing flows. Cartridge construction gives maximum flexibility in mounting.
