Functional Description
A poppet-type hydraulic directional shuttle valve in the form of a screw-in cartridge for use in single acting
cylinder applications. Pressure at port 1(P) opens the ball check valve, allowing uid to pass to port 3(A). The
poppet tightly closes the connection between ports 3(A) and 2(T). If there is no pressure at port 1(P), any
pressure at port 3(A) - like from a cylinder‘s return spring - causes the poppet to shift such that uid can pass
from 3(A) to 2(T) but not from 3(A) and 1(P).
