Parker XV520P-4 Ball Valve 1/4 Inch Fnpt Brass 650 Psi

Product Description

The PARKER XV520P-4 is a standard 2-piece manual ball valve designed for inline shutoff and flow control in plumbing, HVAC, and industrial fluid systems. The body and trim are constructed from brass, offering solid corrosion resistance in water, air, and compatible fluid applications. A lever handle provides quick quarter-turn actuation for fast open and close operation. Seats and seals are made from reinforced polytetrafluoroethylene (PTFE), which handles a wide range of media and temperatures. The valve is rated to a maximum working pressure of 650 psi, making it suitable for moderate- to high-pressure service lines.

This valve is suited for residential and light commercial applications where a reliable inline shutoff is needed on a 1/4 inch pipe run. Typical install scenarios include refrigerant line service ports, compressed air lines, water supply branches, and instrumentation connections. Both end connections are female NPT (FNPT x FNPT), accepting standard threaded pipe fittings on both sides. Licensed plumbers, HVAC technicians, and pipefitters commonly specify this valve for new installations and replacement work where a compact brass ball valve is required.

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 1/4 inch FNPT threaded pipe systems in plumbing, HVAC, and compressed air applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter in accordance with applicable local codes, including IPC and IFGC where relevant. Shut off and depressurize the system completely before removing any existing valve or making new connections. Apply appropriate thread sealant or tape to NPT threads before assembly, and do not overtighten fittings into the brass body. Verify that the valve is in the full open or full closed position after installation and confirm no leaks under system pressure before returning the line to service.
