H44 American Standard Swing Check Valve

Release Date: October 31, 2015

The products of H44H and H44Y American standard stainless steel swing check valves are designed and manufactured in accordance with the requirements of the American National Standards, ANSIB16.34, American Petroleum Institute Standard API16D.

Check valve

The American standard check valve is selected for pipelines with various operating conditions such as petroleum, chemical and thermal power stations with a nominal pressure of 150LB ~ 600LB and an operating temperature of -29 ~ 550 ℃. Applicable medium: water, oil, steam, etc.

Features

American standard check valve products are designed and manufactured according to national standard GB / T12235.

The American standard non-return valve is carefully selected and meets domestic and foreign relevant standards. The overall quality of the material is high.

Various piping flange standards and flange seal types can be used to meet various engineering needs and user requirements.

The sealing pairing is advanced and reasonable. The sealing surfaces of the valve disc and valve seat are made of iron-based alloy or Stellite cobalt-based hard alloy surfacing. long life.

American standard check valve body materials are complete, gaskets can be reasonably selected according to actual operating conditions or user requirements, and can be applied to various pressure, temperature and medium operating conditions.

We can design and manufacture non-return valves with different structural forms and connection forms according to user requirements.
