Wafer Type Check Valve
Introduction:
The double plate wafer check valve is composed of body, disc, stem and spring and other parts. It adopts clamping connection and has compact structure. Due to the short closing stroke of the disc and the spring loading, the closing speed is fast, which can significantly reduce the phenomenon of water hammer. The product has the characteristics of small volume, light weight, sensitive action, reliable sealing, easy installation and so on. It can be installed horizontally or vertically. It can be applied to water, steam, oil, acetic acid, strong oxidizing medium and other media.
Scope of Application:
Double flap wafer check valves are used to prevent media backflow. By choosing different materials, the sandwich check valve can be applied to water, steam, oil, acetic acid, strong oxidizing medium and urea and other media in petrochemical, metallurgy, electric power, light industry, food and other industries.
