Reasonable product structure, reliable sealing, and excellent performance
The sealing pair is advanced and reasonable, and the sealing surfaces of the valve disc and valve seat are made of iron-based alloy or Stellite drill based hard alloy overlay welding surface. It has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance, and long service life.
Various piping flange standards and flange sealing types can be used to meet various engineering needs and user requirements.
The valve body material variety is complete, and the gasket can be reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.
The connection between the pin shaft and valve plate adopts an internal structure, without any external leakage points, making it more reliable to use
Mainly composed of valve body, valve cover, and valve disc. The valve disc is made of rubber coated steel plate and vulcanized by compression molding, which is resistant to erosion and has good sealing performance. The sealing pair adopts an inclined design, which has a short closing time, low noise, reduces water hammer, and is not easy to accumulate debris. Simple structure, easy maintenance and upkeep. This type of check valve is mainly used in water supply and drainage systems and can be installed at the outlet of the water pump to prevent backflow and water hammer damage to the pump.
