API Standard Gate Valve

API standard gate valve is a fully open or fully closed valve. The API standard gate valve controls the medium flow in the pipeline. When the disc is closed, it prevents the medium flow. When the disc is open, the medium can pass through the valve. API standard gate valve can only be fully opened or fully closed, not half opened.

3.The Characteristic of Stainless Steel Flange Gate Valve 

Reliable sealing, excellent performance and beautiful appearance.
Wedge type elastic gate structure is adopted, rolling bearing is set in medium and large diameter, easy to open and close.
After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance.
The gate and valve seat have good abrasion resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life.

All kinds of piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
The valve body material is complete, and the packing and gasket are reasonably selected according to the actual working condition or user's requirements, which can be applied to various pressure, temperature and medium working conditions.
