AM.3.UP.../ AM.3.UP1 - Modular Pilot Operated Check Valves

AM.3.UP type modular check valves allow free flow in one direction by raising a conical seated poppet valve, while in the opposite direction the fluid can return by means of a small piston piloted by the other line pressure (piloted side). They are available on single A and B lines, and double A and B lines (see hydraulic symbols). A pre-opening version is also available (AM3UP1..) only with a 5 bar spring.
