American Standard Check Valve

?CHECK VALVE

H44h American Standard swing check valve is applicable to pipelines under various working conditions such as petroleum, chemical industry and thermal power plant with nominal pressure of class 150-2500lb (pn1.6-16.0mpa) and working temperature of - 196-600 ℃, to prevent backflow of medium.

?Its main structural features are:

1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.

2. The product can choose soft seal or hard seal according to different working conditions. The sealing surface is overlaid with cemented carbide, which has good wear resistance, touch resistance, abrasion resistance and long service life.

3. The opening pressure is small, and the valve disc can be fully opened under a small pressure difference.

4. The built-in pin shaft structure reduces external leakage points and is reliable in use.

5. The nominal pressure is ≥ class 1500Lb (16.0mpa), and the middle chamber adopts a self sealing structure. The sealing performance increases with the increase of pressure, ensuring the sealing performance.

6. Parts materials, flanges and butt weld end sizes can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
