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, at temperatures up to 570°C, prevent backflow of media.

Structural Features

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

2. Sealed face surfacing with Cobalt hard alloy, offering excellent wear and corrosion resistance, good scratch resistance, and a long service life.

3. Internally mounted pinion structure, minimizes external leakage, and is reliable in use.

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

5. Component materials, flanges, and socket weld end dimensions can be reasonably selected according to actual operating conditions or customer requirements to meet various engineering needs.
