Valves › Non-return valves

A non-return valve is a mechanical device, which normally allows fluid (liquid or gas) to flow through a pipe in only one direction.

We propose various types of check valves used in a wide variety of applications.

Although they are available in a wide range of sizes (DN 10 to 300 ; upon under request).

Different type of non return valves:

• Ball non-return valve
• Spring return valve
• Swing check valve
• Disk non-return valve
• Double disk non-return valve
• Diaphragm non-return valve

We are able to provide non-return valves in brass, bronze, aluminum bronze, but also cast iron, nodular iron, stainless steel, forged or cast steel for installations ranging from DN 10 to DN 300 (upon under request).

These valves are designed for mounting between flanges according to DIN, ANSI or JIS standards. We propose, in addition, flanged, threaded and welded (SW or BW) connections.
