Parker XV501P-8 Ball Valve 1/2 Inch Brass 600 Psi

Product Description

The PARKER XV501P-8 is a standard manual ball valve designed for inline shutoff and flow control in plumbing, HVAC, and industrial piping systems. Built with a brass body, brass trim, and brass lever handle, it connects via 1/2 inch MNPT x FNPT end connections for straightforward threaded installation. The reinforced polytetrafluoroethylene (PTFE) seat and seal materials provide reliable, low-friction sealing across a wide range of media and temperatures. This valve is rated for a maximum working pressure of 600 psi, making it suitable for demanding commercial and industrial service. Licensed plumbers and HVAC technicians typically specify this valve for hydronic, gas, or compressed-air piping runs where a compact, quarter-turn shutoff is required.

This valve is suited for residential and light commercial applications including hydronic heating systems, compressed-air distribution, potable water lines, and general-purpose fluid control. The MNPT x FNPT configuration allows it to thread directly onto male pipe stubs or female-threaded fittings without adapters. The lever handle provides a clear visual indication of open and closed positions, which simplifies maintenance and inspection on crowded mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes, IPC, and IFGC requirements. Shut off and depressurize the supply line completely before removing any existing valve or making threaded connections. Apply appropriate thread sealant or PTFE tape to male threads before assembly, and torque connections using pipe wrenches per standard plumbing practice. Do not exceed the rated 600 psi working pressure, and verify media compatibility with PTFE seals before installation on chemical service lines.
