The role of the muffler check valve is to allow only one direction of the medium, and prevent the direction of flow. Normally, the valve works automatically and the disc opens under the action of fluid pressure flowing in one direction. When the fluid flows in the opposite direction, the pressure of the fluid and the self-coincidence of the disc disc ACTS on the seat, thus cutting off the flow. It is not suitable for medium containing solid particles and high viscosity.
Silencing check valve is mainly composed of valve body, valve seat, guide body, disc, bearing and spring. Internal runner adopts streamlined design with minimal pressure loss. Disc opening and closing stroke is very short, can be closed quickly when stopping the pump, to prevent the huge water hammer, with the silent closing characteristics. The valve is mainly used for water supply and drainage, fire protection, heating and ventilation systems. Can be installed at the pump outlet to prevent backflow and water hammer damage to the pump.
Scope of use: this product can be used in water supply and drainage system, fire fighting, heating and ventilation, chemical, power plant, metallurgy, petrochemical and other industries, generally installed in the outlet of the pump, to prevent backflow water and water hammer damage to the pump.
