Parker 2A-V4LN-SS Straight Needle Valve 1/8 in 5000 Psi

Product Description

The PARKER 2A-V4LN-SS is a straight-pattern needle valve designed for precise flow control in high-pressure fluid and gas systems. Built from 316 stainless steel, it handles working pressures up to 5000 psi, making it suitable for demanding industrial and mechanical service environments. The 1/8 inch pipe connection keeps it compact for tight installations. Licensed plumbers, pipefitters, and instrumentation technicians commonly install this valve in process lines, test manifolds, and instrument isolation applications where accurate shutoff and flow metering are required.

This needle valve fits inline applications requiring a straight-body configuration with 1/8 inch pipe connections. It is well suited for hydraulic test panels, pneumatic instrument lines, refrigeration service ports, and chemical process systems where a bubble-tight shutoff or fine throttling is needed. The 316 stainless steel construction resists corrosion from moisture, mild acids, and chloride-bearing environments, broadening its range of compatible service fluids.

Key Features

• Straight-body design for direct inline installation with minimal flow path restriction
• 5000 psi maximum working pressure rating for high-pressure service
• 1/8 inch pipe size connection suitable for compact instrument and test line applications
• 316 stainless steel construction for corrosion resistance in harsh or wet environments
• Needle-type throttling element enables fine, repeatable flow adjustment

Compatibility

Designed as an OEM-style replacement or direct-fit needle valve for 1/8 inch pipe systems rated to 5000 psi. Consult system documentation to confirm pressure ratings, thread form, and fluid compatibility before installation.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified instrumentation technician in accordance with applicable codes. Depressurize and isolate the system completely before removing or installing any valve. Apply thread sealant appropriate for the service fluid and pressure rating; do not overtighten fittings, as 1/8 inch pipe threads are easily damaged. Verify that the valve body and seat materials are compatible with the process fluid before placing the valve in service.
