Check valves are designed to allow flow in one direction only, preventing backflow in case the fluid in the line reverses direction.

These automatic valves do not require any operator – manual or automatic – to open and close, making them ideal for situations where there is a loss of electricity or pneumatic air supply.

It is essential to consider the type of check valve to choose:

• Piston-Disc/Forged Ball Check Valve: offers excellent resistance and reliable performance, suitable for high-pressure and high-temperature applications.
• Forged Swing Check Valve: ideal for heavy fluids, ensures a tight seal with a robust and durable construction.
• Cast Swing Check Valve: suitable for less demanding applications, offers a balance between cost and performance.
• Dual Disc Check Valve: suitable for a wide range of pressure, temperature, and environmental applications.
• Spring Check Valve: provides fast and reliable closing action, suitable for plants requiring immediate responses.
