Applications

 Non-return valve is designed for use in stainless steel pipe installations to prevent reverse flow.

Operating principles:

When the lower pressure of valve stem over the upper pressure and spring force,check valve opens.

When the upper pressure equal to the lower pressure ,check valve closes.

A higher reverse pressure acts on the valve stem and causes valve to close.

Standard design:

Check valve has two parts jointed together by clamp and sealed with the special gasket .This series has welded ,clamped and threaded type,suit for kinds of pipeline connection.

Technical data:

If the check valves are installed in a vertical pipe,it needs approximately equal pressure 6Kpa to open.Maximum pressure for conveying material is 1000Kpa,Using temperature scope fo-10℃-135℃.
