In a hydraulic system, shut-off valves serve to check flow in a preferred direction and allow free flow in the opposite direction. They are designated as check valves. The shut-off valves are designed as poppet valves and therefore provide leak free closure. A ball or poppet is generally used as the closing element.

Three Port Check Valve Cartridges - CX*C and CX*E Sun CX*C nose-to-side free flow and CX*E side-to -nose free flow "cheater" check valves have similar performance characteristics to CX*A and CX*D cartridges, respectively. However, they fit in three port cavities, but port 3 is blocked. Performance parame-

The C Series Check Valve port options include ISO 6149, NPT, BSPP, BSPT and SAE. Parker offers superior brass, steel and stainless-steel check valves in a wide variety of sizes and ports. The steel C Series Check Valve comes standard with a black oxide finish. Markets: • Power Gen • Machine Tools • Factory automation • Vehicle Assembly

The purpose of a check valve is to permit free flow in one direction and prevent any flow in the opposite direction. • Fluid flows through the valve in the space between the seat and poppet. • A light spring holds the poppet in the closed position. In the free-flow direction, the fluid pressure overcomes the spring force at about 5 psi.

CHECK VALVES. Shut-off valves from HYDAC are poppet and spool valves for the controlled opening or closing of lines and other hydraulic components. They control inlet, dischrage or outlet of hydraulic fluids. Check valves with hardened seat. Check valves pilot to open.

Abstract. Hydraulic valves are mechanical devices that are used to regulate the flow of fluid within a hydraulic circuit or system. They can be used to completely close a line, to redirect
