American standard large-diameter check valve
Other Products
I. Overview of American Standard Large Diameter Check Valves:
① The design and manufacture of the product comply with the requirements of American National Standard ANSI B16.34 and American Petroleum Institute Standard API 16D.
② The valve disc is swing-type, with a straight flow passage, and can be installed on both horizontal and vertical pipelines.
③ The rocker pin adopts an internal structure, which reduces the disadvantage of external leakage.
④ The valve body and bonnet are bolted. For high-pressure conditions with a rating greater than Class 600Lb, the middle flange adopts an internal pressure self-sealing structure, making the product small in size, light in weight, and reliable in sealing. Standards (fire protection, anti-static)
