Specifications:
Applications:
•Stainless steel sanitary 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 closes.
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,suits 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 for -10℃~+135℃.
