Flanged and welded non-return valves

The body lengths of flanged non-return valves conform to standard dimensions, allowing the replacement of damaged valves with new ones without piping modification works. In new building projects, it is often more economically feasible to use flanged non-return valves, since the structure of such valves is lighter and they are more cost-effective.

Welding prevents flange leaks

In many processes, one has to be sure that the non-return valve will not start leaking in the flange seat. For such applications, welded non-return valves are suitable. Our range contains suitable valves made of different materials up to the pressure rating PN 500.

Our product range also covers ASME non-return valves up to the pressure rating 2500#, including non-return valves lockable in the open position and closable non-return valves.
