Contact All Suppliers Check Valves

Check valves normally allow fluids to flow through it in only one direction. They are two-port valves, one port for fluid to enter and one for fluid to exit. There are various types of check valves that can be used across several applications and industries. They are usually very small and inexpensive and usually work automatically with no need for a person operating them. Due to this, they don't have any handle or stem. They are usually made from plastic or metal. Check valves are designed and prepared for crack pressure, which is the minimum upstream pressure at which the valve will operate.
