Parker 8A-V8LN-SS Needle Valve 1/2 in Compression Ss 5000 Psi

Product Description

The PARKER 8A-V8LN-SS is a straight-pattern needle valve designed for precise flow control in high-pressure fluid and gas systems. Built with a 316 stainless steel body and a polytetrafluoroethylene (PTFE) seal, it handles working pressures up to 5,000 psi. The round handle provides manual throttling control, and the compression-end connections make installation straightforward without threading pipe ends. At 3.06 inches overall length and 4.18 inches overall height, this valve fits compact installations without sacrificing pressure capacity. Licensed plumbers, pipefitters, and HVAC technicians install this type of valve in instrumentation, refrigeration, and process piping applications.

This valve is suited for residential and commercial applications where corrosion resistance and high-pressure performance are required. The stainless steel body and PTFE seal make it appropriate for use with aggressive media, including mildly corrosive fluids and gases. It is commonly installed in instrument tubing runs, hydraulic lines, compressed air systems, and refrigerant circuits that require dependable shutoff and metering capability. The 1/2-inch compression end connections are compatible with standard tubing installations in process and HVAC piping systems.

Key Features

• Straight-pattern flow path for in-line installation
• 316 stainless steel body for corrosion resistance in demanding environments
• PTFE seal provides chemical compatibility with a wide range of media
• Rated to 5,000 psi maximum working pressure
• Round handle for manual flow throttling and shutoff
• Compression-end connections for 1/2-inch tubing

Compatibility

Designed as an OEM-style replacement or direct-install needle valve for 1/2-inch compression tubing systems requiring high-pressure shutoff and flow control in process, HVAC, or instrumentation piping.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified HVAC technician. Depressurize and isolate the line completely before removing any existing valve or fitting. Compression fittings should be seated and tightened using appropriate tubing wrenches without over-torquing. Follow applicable IPC or IFGC guidelines for the specific piping system and media being handled.
