American Standard Check Valve

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

Structural Features

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

2. Hard-facing with a Co-based carbide seal face, offering excellent wear, corrosion, and abrasion resistance, with a long service life.

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

4. When the pressure is Class 1500LB, the valve cavity employs an auto-tightening sealing 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.
