AM.7.UP type modular check valves
allow free flow in one direction by
lifting a seated poppet, while in the
opposite direction the fluid can return
by means of a small piston piloted by
the other line pressure (piloted side).
The cast valve body allows limited
pressure drops during the fluid flow
through the various P/A/B/T lines.
They are available on single A or B
lines, and on double A and B lines
(see hydraulic symbols).
