Material: the check valve is made of PVDF plastic, the internal spool is made of fluoroelastomer (FKM), PVDF plastic has high hardness, good heat and corrosion resistance, strong resistance to acid and alkali, and some resistance to organic solvents.
The right size: you get 5 check valves in 3/8-inch, 1/16-inch, 3/16-inch, 5/16-inch, 1/8-inch, 1/4-inch sizes, enough for you to use the check valves in different situations, preventing fluid backflow
Function: The check valve is used in fluid system to prevent backflow of fluid, or used in pneumatic system to prevent backflow of compressed air; the check valve applies to the temperature range of -40 degrees Celsius to 120 degrees Celsius
Wide range of uses: check valves can be used in ozone sterilization, water treatment, air purification, automotive parts, machinery industry, household appliances, etc., to effectively prevent media backflow
The opening pressure: <1Kpa, closing pressure: >1Kpa
