What is a PN10 / PN16 Stainless Steel Wafer Check Valve?

A wafer check valve is a mechanical device installed between two flanges in a pipeline. It allows fluid to flow in one direction and automatically prevents reverse flow. The PN10 and PN16 ratings indicate the nominal pressure class of the valve:

• PN10 – Suitable for systems operating up to 10 bar pressure.
• PN16 – Suitable for systems operating up to 16 bar pressure.

The stainless steel construction ensures corrosion resistance, strength, and durability even in aggressive environments.
