Hard Seat, High Flow, In Line Hydraulic Check Valves - CV Series

CV Series Hydraulic Check Valves (3,000) psi are in line, one way valves that have a two piece modular design. The larger body results in less pressure drop and increased performance. These hydraulic check valves have standard spring crack pressures of 5 and 65 psi. The CV Series are available in a range of sizes up to 1"" and flow capacities to 100 gpm. CV Series Hydraulic Check valves are important components that are often overlooked when building a fluid system. A check valve can optimize system performance in the following ways: • Ensure hydraulic fluid flows in only one direction • Eliminate potential damage from back pressure • Isolate sections of a system or system components Basic check valve construction consists of a valve body with an inlet and an outlet port. Inside, a moveable poppet valve is controlled by spring pressure. In most cases the valve is normally closed, opening when the fluid pressure is greater than the spring force (crack pressure), thus allowing the fluid to flow in only one direction. When reverse flow attempts to enter though the outlet the poppet closes and flow through the valve is stopped. Hard seat, hydraulic check valves utilize a durable metal to metal seal to withstand high flow surges and provide longer service life.
