Parker C552204 Instrumentation Plug Valve 250 Psi

Product Description

The PARKER C552204 is a 1/4-inch instrumentation plug valve designed for precise flow shutoff in instrumentation and process piping systems. Built with a brass body and nitrile seals, it connects via FNPT x MNPT end connections and operates with a lever handle for quick quarter-turn actuation. Rated to 250 psi maximum working pressure, this valve handles a wide service temperature range from -40 degrees F to 175 degrees F. It is installed by pipefitters, instrumentation technicians, and plumbers working on control, sensing, and sampling lines in industrial and commercial applications.

The C552204 is suited for instrumentation tubing and small-bore process lines where reliable shutoff is required. Its brass body construction makes it appropriate for use with air, water, oil, and compatible gases within the rated pressure and temperature limits. The lever handle design allows for fast visual confirmation of valve position during service and commissioning. This valve ships in a package quantity of two units per order.

Installation Notes

Installation should be performed by a licensed pipefitter or instrumentation technician in accordance with applicable local codes and system design requirements. Depressurize and isolate the line completely before removing or installing any valve. Apply appropriate thread sealant to NPT connections per system fluid compatibility requirements. Verify flow direction and valve orientation before returning the line to service.
