Parker XV501SS-4 Ball Valve 1/4 Inch Full Port 2000 Psi

Product Description

The PARKER XV501SS-4 is a 2-piece, full-port manual ball valve designed for demanding fluid and gas control applications. Built with a 316 stainless steel body and trim, it delivers a maximum working pressure of 2000 psi (138 bar) and handles temperatures down to 0 degrees F. The lever handle provides fast quarter-turn shutoff, and the reinforced PTFE seats and seals maintain a reliable bubble-tight closure across a wide range of media. This valve is suited for industrial process lines, instrumentation, and corrosive-service piping where stainless steel construction is required.

The XV501SS-4 fits 1/4 inch pipe in systems requiring a male NPT inlet and female NPT outlet connection. Its full-port bore minimizes pressure drop across the valve, making it appropriate for flow-sensitive installations. Common applications include chemical processing, offshore and marine environments, HVAC hydronic systems, compressed-air lines, and any service governed by NACE MR-01-75 corrosion-resistance standards. Licensed plumbers, pipefitters, and instrumentation technicians typically specify this valve in both commercial and industrial settings.

Key Features

• 316 stainless steel body, trim, and handle for corrosion resistance in aggressive media
• Full-port design minimizes flow restriction and pressure drop
Reinforced PTFE seats and seals for chemical compatibility and long service life
• 2000 psi maximum working pressure (138 bar)
• Quarter-turn lever handle for fast manual actuation
• Compliant with NACE MR-01-75 for sour-service and corrosive-environment installations

Compatibility

Designed as a standard OEM-style replacement or new-installation ball valve for 1/4 inch NPT piping systems requiring full-port, 2-piece stainless steel construction with MNPT x FNPT end connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes such as the IPC or relevant industrial piping standards. Depressurize and isolate the line completely before removing an existing valve or making connections. Apply thread sealant rated for the service media to the male NPT threads; avoid over-tightening, which can crack fittings or distort seals. Verify the flow-direction arrow on the valve body before final makeup if applicable, and confirm the system is at zero pressure before returning to service.
