American standard manual gate valve

American standard gate valve features:

1. The design and manufacture of the product meet the requirements of American national standard ANSI B16.34, American Petroleum Institute standards API6D and API600.

2. Compact structure, small size, good rigidity, safe and reliable sealing.

3. The closing part (gate) is of elastic structure, which can automatically compensate the valve body deformation caused by abnormal load or temperature during operation. Therefore, the seal is reliable and the ram wedge will not be generated.

4. For manual valves with a diameter greater than or equal to NPS10 ", a pressure class of 150 pounds, and a diameter greater than or equal to NPS6", a pressure class of 600~2500 pounds, the operating device is equipped with rolling bearings, which is easy to open and close.

5. The materials of main body, internal parts, fillers, gaskets and fasteners can be reasonably combined according to user requirements or actual working conditions.

6. For gate valves with NPS ≤ 10 ", the valve seat can be a replaceable internal thread connection valve seat, which can be arbitrarily combined and matched with the sealing surface material of the closing part to meet the working conditions and extend the service life.
