2pcs Two color silicone membrane microplastic one-way valve liquid plastic one-way valve check valve small pneumatic valve

Performance※ Normal performance under 25 ℃ to 60 ℃,Strong resistance to acid, alkali, salt corrosion ability Application ※Check valve is used in fluid system to prevent reverse flow fluid, or used in pneumatic system to prevent reverse flow of compressed air. Material: This product is made of ABS plastic, the internal valve core is made of silicone, good heat resistance and corrosion resistance, strong acid and alkali resistance, and to a certain extent resistant to organic solvents. It works normally at 25 degree centigrade to 60 degree centigrade, and has strong resistance to acid, alkali and salt corrosion. Note: When installing the check valve, pay special attention to the flow direction of the medium, and the normal flow direction of the medium should be consistent with the direction of the arrow indicated on the valve body, otherwise the normal flow of the medium will be cut off. Check valves are used to prevent fluid backflow in fluid systems or compressed air backflow in pneumatic systems. Wide range of uses: Check valves can be used in water treatment, air purification, auto parts, machinery industry, household appliances, etc., effectively preventing media backflow.
