Check Valves

Check Valves, 800 PSI


Check Valves






Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.  There are various types of check valves used in a wide variety of applications.

Also, Check valves are often part of common household items.  Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive.

In addition, Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem.  Finally, The bodies (external shells) of most check valves are made of plastic or metal.

Also, Check Valves comes in General purpose stainless steel flanged, NPT, socket, Tri-clamp end check valves, springed or swing type.  Also, High quality, durable design check valve.

Also, they are ideal for application in vacuum pumps, compressed air and gas systems as well as in water systems where low head loss and elimination of water hammer are desirable.

Finally, the Full Port Check Valves provide more flow and lower pressure drops than conventional check valves.  In addition, our elastomer hinge check valve design takes performance to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valve’s open area and flow coefficient (CV)
