Parker XV590P-6 Ball Valve 3/8 Inch Mnpt X Fnpt Brass 250 Psi

Product Description

The PARKER XV590P-6 is a standard manual ball valve designed for reliable on/off flow control in plumbing, HVAC, and industrial piping systems. Built with a 2-piece brass body and reinforced PTFE seats and seals, this valve handles working pressures up to 250 psi across a wide operating temperature range, down to -50 degrees F. The 3/8 inch MNPT x FNPT end connections make it straightforward to install inline on threaded pipe runs. The tee-style steel handle provides a clear open/closed visual indicator and firm grip during manual operation. Licensed plumbers, HVAC technicians, and pipefitters routinely specify this valve type for service isolation, zone control, and maintenance shutoff applications.

This valve is suited for residential and light commercial plumbing and HVAC piping where a compact, threaded shutoff is required. The 3/8 inch pipe size fits common branch lines, supply connections, and equipment service ports. Its brass construction makes it appropriate for water, air, and compatible fluid service where corrosion resistance and pressure durability are priorities. The reinforced PTFE seats provide a bubble-tight shutoff under rated conditions, reducing the risk of service call callbacks related to valve leakage.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and IFGC or IPC guidelines where relevant. Shut off system pressure and depressurize the line completely before removing any existing valve or making threaded connections. Apply thread sealant or tape rated for the service fluid to all MNPT connections. Do not exceed the rated working pressure of 250 psi in the installed system.
