Screws and studs Ch. IV page 21
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 or B lines, and double A and B lines (see
hydraulic symbols).
A pre-opening version is also available (AM3UP1..) only with 5 bar spring.
Max. operating pressure 350 bar Minimum opening pressure spring 1 1 bar Minimum opening pressure spring 5
