Rubber flap check valve

The rubber flap check valve is mainly composed of three parts: valve body, valve cover and rubber flap. The rubber flap is made of steel plate, steel rod and reinforced nylon cloth as the substrate, and the outer layer is covered with rubber. The valve flap switch can be used for 1 million times. The valve adopts the full-flow area design, which has the characteristics of small head loss, easy accumulation of debris and easy maintenance. Rubber flap check valve is mainly suitable for water supply and drainage system, can be installed in the water pump outlet to prevent water backflow and water hammer phenomenon damage to the pump. In addition, the valve can also be installed on the by-pass pipe of the reservoir inlet pipe to prevent the pool water from flowing back into the water supply system.The principle of rubber flap check valve is to open and close the valve through the pressure generated by the fluid flow, and to control the fluid flow by controlling the opening of the switch, and to work automatically in the pipeline system. The rubber flap check valve can only be used in the one-way flow of the fluid pipeline, with safe and reliable, stable work, simple and practical characteristics, for the transportation of the pipeline system provides security.

HC44X (SFCV) rubber disc check valve is composed of body, valve cover, valve disc and spring, etc. It is mainly used in the pipe outlet of water supply and drainage system, petroleum, chemical industry, etc., to prevent media counterflow. Because the sealing ring of this product adopts the inclined design, the closing time is short, and the water hammer pressure can be reduced. The valve disc is made of nitrile butadiene rubber and steel plate by pressing at high temperature, which is resistant to erosion, good sealing performance, simple product structure, convenient maintenance, repair and transportation.
