AM.3.UD type modular check valves

allow one way free flow, while flow in

the opposite direction is prevented by

means of a conical seated poppet.

They are available on single A, B, P

and T lines, and on double A and B, P

and T lines (see hydraulic symbols).

1 bar spring is standard, while a 5 bar

rated spring is available on request.
