Brief introduction of API hard seal electric gate valve

Gate valve is one of the widely used industrial valves in fluid transport projects to cut off the mediums. Gate valve has compact structure, reasonable design, smooth passage, large flow coefficient, small flow resistance, simple structure, and it is convenient to repair.

Characteristics of API hard seal electric gate valves:

1. compact structure, reasonable design, smooth passage, large flow coefficient, small flow resistance, simple structure, easy to maintain.

2. for large diameter gate valve, it can be set with rolling bearings, to make it easy to open and close.

3. The valve body has a complete variety of materials, and the packing and gasket are reasonably selected according to the actual working conditions or user’s requirements, and can be used in various pressure, temperature and mediums working conditions.

Applications of API hard-seal electric gate valve:

API hard seal electric gate valve is suitable for pipelines of various mediums such as water, steam, oils, nitric acid, acetic acid, urea, and strong oxidizing mediums, etc.
