Swivel Type H84X Rubber Flap Check Valve Grooved Type
I. Overview
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.

3. Use and maintenance
Fire gate valves are often used in automatic sprinkler fire pipeline systems, rotating handwheels to control the opening and closing of water sources in water supply pipelines.
4. Installation:
(1) Handwheels, handles and transmission mechanisms are not allowed to be used for lifting, and collisions are strictly prohibited.
(2) Before installation, check whether the product model, tag and specification are consistent, and check whether the parts of the whole machine are defective and loose.
(3) Before installation, the pipeline should be cleaned, and there should be enough straight pipe section at the valve inlet, and equipped with a filter.
(4) The installation site should consider the comprehensive personnel and equipment, even if it is operated, it is conducive to disassembly and maintenance.
(5) The signal box is connected to the fire protection system circuit.
