Re-seal pressure is defined as the downstream pressure at which the check valve closes bubble-tight. Example: For a valve with a spring having a rated cracking pressure of 25 psig (1.72 bar), the actual cracking pressure ranges between 20 and 30 psig (1.38 and...

CO Series Check Valves Introduction Parker CO Series Check Valves are designed for uni-directional flow control of fluids and gases in industries such as chemical processing, oil and gas production and transmission, pharmaceutical, pulp and paper, power and utilities. The CO Series Check Valve is particularly suitable for applications requiring high integrity leak rates and re-sealing capabilities. Seal integrity across the seat and to atmosphere is tested to 4 x 10-9 std atm-cc/sec (4 x 10-10 kPa – L/sec) for the CO4L with fluorocarbon rubber seals. All other sizes and seal materials are tested...
