JIS CHECK VALVE
Swing check valve, also called swing check valve, is a manually operated two-way flow control valve. The operation of the valve body can be reversed at any time. An important feature of this type of product is that it does not form an air tight seal or free passage until the position rod is rotated by 90 degrees to change its position from "closed" to "open".
Product introduction:
We are a professional manufacturer of various stainless steel 304 JIS swing check valves. Swing check valve is a manual two-way flow control valve. The swing arm moves up and down under the action of spring; When the valve rod is rotated by 90 degrees to change its position from "closed" to "open", the disc valve can be automatically closed or opened under the action of spring force, thus forming an air tight seal or free passage. Airtight or free passage can be reversed at any time.
Product features:
1. simple operation
JIS check valve is made of stainless steel, with simple and reliable operation. In open or closed mode, there is no adhesion or leakage on the valve seat surface. It is an irreplaceable part to ensure the smooth progress of our manufacturing and transportation process at any time.
2. stainless steel 304 JIS swing check valve is the connection point of the air inlet or exhaust port of industrial valve. This is the most popular check valve type in most industrial applications because of its excellent suction, high flow rate and small space requirements. The gate valve rotates around the vertical axis, and the valve seat is opened or closed by a screw system similar to the tank cover. Compared with other types of check valves, its design greatly reduces the leakage when it is fully open.
3. our swing check valve is made of stainless steel. They can be used for solid control and pressure regulation of septic tank systems, leachate field pipelines and drainage pipelines. JIS design ensures long service life and wide compatibility with a wide range of liquids, including chemicals and petroleum. The valve body is made of 304 stainless steel, with corrosion resistance, chemical corrosion resistance and strength. Test the JIS plug at 250 ° f (121 ° C) for 30 minutes. The new check valve used in the production line is safe and reliable. Maintain tight shutoff during normal operation to ensure that pressure does not leak. Automatic locking in case of power failure to prevent accidental pressure leakage. It is an ideal choice for commercial and industrial wells, residential well pumps and groundwater monitoring systems.
4. stainless steel 304 is a kind of carbon steel and low alloy steel with improved corrosion resistance. Its corrosion resistance in all media is better than that of Xingrui or stainless steel, except for sulfuric acid at high temperature. Stainless steel has good strength and toughness at room temperature, but its hardness, tensile strength and wear resistance decrease at high temperature. It has good oxidation resistance in air. Stainless steel is the most widely used anticorrosive material and has many special uses.
5. swing check valve is a single port butterfly valve, which can be used with electromagnetic control or spring actuator. These valves are designed to facilitate the user to isolate the pipeline and can be installed by any standard method, including flange or bellows. Features. 34 stainless steel structure, corrosion resistance, high strength and durability. Port sizes are available in 2 -, 3 -, and 4-inch diameters.
