Parker BD-XV500P-4-1 Ball Valve 1/4 in Npt Brass

Product Description

The PARKER BD-XV500P-4-1 is a full-port manual ball valve designed for inline flow control in plumbing, HVAC, and industrial fluid systems. It features a 2-piece brass body with a reinforced PTFE (Teflon) seat and a lever handle for quick quarter-turn shutoff. The full-port design ensures minimal pressure drop across the valve by maintaining an unobstructed flow path equal to the pipe bore. Sized at 1/4 inch NPT, this valve is suited for applications where reliable manual isolation is required. Licensed plumbers, HVAC technicians, and pipefitters commonly specify this type of valve for service lines, equipment isolation, and branch circuits.

This valve is appropriate for residential and light commercial installations where a compact, manually operated shutoff is needed on a 1/4 inch NPT line. Typical applications include refrigerant service ports, condensate drain lines, water supply branches, compressed air circuits, and other low-to-moderate pressure fluid systems. The lever handle provides a clear open or closed visual indicator at a glance, making it practical in tight mechanical spaces where valve position must be confirmed quickly.

Key Features

• Full-port ball design minimizes flow restriction and pressure drop
• 2-piece brass body provides corrosion resistance for water, air, and compatible fluid service
• Reinforced PTFE seat delivers low-friction operation and a reliable seal
• Lever handle allows quick quarter-turn shutoff with clear open or closed indication
• 1/4 inch NPT end connections for standard threaded pipe installation

Compatibility

Designed as an OEM-style manual shutoff valve for 1/4 inch NPT threaded piping systems in residential and commercial HVAC, plumbing, and fluid handling applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where relevant. Shut off system pressure and depressurize the line completely before installing or removing the valve. Apply thread sealant or PTFE tape to male NPT threads per standard practice, and avoid over-tightening to prevent damage to the brass body or seat. Confirm lever handle orientation after installation to ensure the valve opens and closes fully without obstruction from adjacent components.
