Stainless steel check valves are used to make valves unblocked or blocked by rotating valve stems. It can be made of large diameter ball valves with 90 angle. As the switch of ball valves is light in small volume. So, it can be made ones with large diameter, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are usually closed, and it is not easy to be eroded by medium.
Stainless steel check valves are divided into low pressure stainless steel check valves and high pressure stainless steel check valves. Low pressure stainless steel check valves are not only widely selected materials, but also interior materials are color coated with nickel 316 material and sealing ring using special polymerization data. The valve is not only corrosion resistant, strong anti vulcanization ability, fire prevention, static resistance and sealing performance, wide range of pressure and temperature, complete diameter and reducing diameter. It can be equipped with various driving devices. It is an ideal valve selection for chemical and petroleum torch refining and natural gas mining and transportation system.
Stainless steel check valves are mainly used in the pipeline to cut off, distribute and change the direction of medium flow. The inner cavity of the valve body can be discharged outwards by using the self-contained discharge valve. The pivot shaft adopts the protection structure of anti blow out to prevent leakage effectively. The bearing with low friction coefficient reduces the torque to the minimum and facilitates the valve opening and closing. The stainless steel check valve stem is effectively contacted with the valve body, which makes the static and electrical grounding device have superior performance, excellent performance, high reliability, wide use and reasonable price and so on. Stainless steel check valves are mainly used in chemical industry, petroleum, natural gas, metallurgy and other industries and long-term natural gas pipeline with hydrogen sulfide medium, many impurities and serious corrosion.
Installation and use notes of stainless steel check valves:
1. The lifting vertical disc check valve shall be installed on the vertical pipe.
2. The lifting type horizontal disc check valve shall be installed on the horizontal pipe.
3. Pay attention to the direction of medium flow during installation in accordance with the direction of arrow on the valve body.
4. Do not make the check valve bear weight in the pipeline. Large check valves shall be independently supported so that they are not affected by the pressure generated by the pipe system.
