Product overview
The stainless steel vertical check valve is normally closed, and the valve is opened due to the pressure of the medium at the inlet end of the pipeline. When the pressure of the medium at the inlet end is lower than the outlet end, the spring pushes the spool to the valve seat to close the valve and prevent the medium from flowing back, so it plays a check role. This valve can be installed vertically or horizontally because it adopts spring support spool.
Product features
1. The sealing pair of stainless steel vertical check valve is advanced and reasonable, and the sealing surface of valve disc and seat is made of iron-based alloy or Stellite cobalt-based carbide overlay welding surface, which has good wear resistance, high temperature resistance, corrosion resistance, good scratch resistance and long service life.
2. Stainless steel vertical check valve is designed and manufactured according to the standard, and can adopt various piping flange standards and flange sealing types to meet various engineering needs and user requirements. The valve body material is complete, and the gasket can be reasonably selected according to the actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.
