Stainless Steel Gate Valve
Stainless steel is one of the most durable materials used in industrial valves, used to provide a tight shut-off in applications with extreme conditions. It is used to handle different types of medium, such as chemicals, corrosive and abrasive medium, slurries, and mixed solids. Because of its resilience, it is used in an array of industrial applications like oil and gas industry, chemical and pharmaceuticals, marine, water and wastewater treatment, and manufacturing industries.

Features:
- The sealing surface of the gate and seat is made of cemented carbide overlay welding of different hardness, which is well sealed and long in use;
- The valve stem is tempered and surface nitride, and has good corrosion resistance, scratch resistance and wear resistance;
- Flexible gate structure, medium and large diameter thrust bearings are set, the friction force is small, and it is equipped with a handwheel, easy to open and close.
- It can adopt piping flange standard and flange sealing surface form, which meets the engineering needs and user requirements.
