Swivel Type H84X Rubber Flap Check Valve Grooved Type
H84X (SFCV) grooved rubber disc check valve is composed of valve body, bonnet, disc and spring, etc., which is mainly used at the pipeline outlet of water supply and drainage systems, petroleum, chemical and other industrial sectors to prevent medium backflow. Due to the inclined design of the sealing ring, the closing time is short, which reduces the water hammer pressure. The valve disc is made of nitrile rubber and steel plate pressed at high temperature, which is wash-out resistant, has good sealing performance, and the product structure is simple, and the maintenance, repair and transportation are very convenient.
