Parker's C Series check valves are designed for uni-directional flow control of critical fluids and gases.
Parker's C Series Check Valves are designed as a compact, inline check valve. These check valves provide uni-directional flow control of fluids and gases. To help prevent improper installation, all check valves have a flow arrow label with the valve's crack pressure rating permanently attached. The availability of a wide range of seat materials provide the system designer a variety of uses over a standard, general purpose check valve.
