Parker 2F-V4LN-SS Needle Valve 1/8 in Fnpt Stainless Steel

Product Description

The PARKER 2F-V4LN-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, this valve handles working pressures up to 5,000 psi, making it suitable for demanding process and instrumentation applications. The round handle provides tactile control for fine throttling adjustments. Female NPT connections on both ends simplify inline installation. At 1.62 inches overall length and 3.06 inches overall height, the compact envelope fits tight plumbing runs. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers of this component.

This valve is intended for use in instrumentation lines, process piping, hydraulic systems, and fluid sampling applications where corrosion resistance and leak-tight shutoff are required. The 1/8 inch FNPT x FNPT port configuration is common in low-flow control circuits, gauge isolation, and instrument root valve applications found in both commercial and industrial settings. Its stainless steel construction suits environments where contact with aggressive media or moisture is a concern.

Key Features

• 316 stainless steel body for corrosion resistance in aggressive service environments
• PTFE seal rated for chemical compatibility across a broad range of media
• Maximum working pressure of 5,000 psi for high-pressure instrumentation service
• Straight-pattern flow path for inline installation without directional change
• 1/8 inch FNPT x FNPT connections for direct threaded makeup
• Round handle for precise manual throttling and shutoff control

Compatibility

Designed as an OEM-style needle valve for 1/8 inch female NPT instrumentation and process piping applications requiring stainless steel construction and high-pressure rated shutoff.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician in accordance with applicable piping codes. Depressurize and isolate the system fully before removing or installing any valve. Apply thread sealant appropriate for the service media and rated pressure on NPT male threads before makeup. Do not exceed the 5,000 psi maximum working pressure rating under any operating condition.
