ASME Check Valve

ASME standard check valves are suitable for pressure classes 150 to 2500 LB, operating temperature -46On pipelines in the oil, chemical, fertilizer, and power industries, etc., at temperatures up to 570°C, prevent backflow of the medium.

Structural Features

The product features a reasonable structure, reliable sealing, excellent performance, and an aesthetically pleasing design.

2. Sealed surface surfacing with Co-based hard alloy, featuring excellent wear, corrosion resistance, and scratch resistance with a long service life.

3. Internally fitted pinion structure for reduced external leakage and reliable operation.

4. At a pressure of Class 1500LB, the valve cavity utilizes an auto-tightening sealing structure. The higher the medium pressure, the better the sealing performance.

5. The material of the parts and the dimensions of the flanges and weld ends can be reasonably selected according to the actual operating conditions or customer requirements, meeting various engineering needs.
