Parker 2A-V4LN-B Straight Needle Valve 3000 Psi 1/8 in

Product Description

The PARKER 2A-V4LN-B is a straight-pattern needle valve designed for precise flow control in high-pressure fluid and gas systems. Rated to a maximum working pressure of 3000 psi, it threads into 1/8 inch pipe connections and provides repeatable shutoff and throttling. Its compact, straight-body configuration suits tight installations where inline flow regulation is required. Licensed plumbers, pipefitters, and industrial maintenance technicians typically specify this valve for hydraulic, pneumatic, refrigeration, and instrumentation service lines where fine metering control is critical.

This needle valve fits residential and commercial applications involving compressed air, hydraulic fluid, fuel gas, or instrumentation tubing at 1/8 inch pipe connections. Its straight-body style allows direct inline installation without additional fittings or adapters. Common install scenarios include pressure gauge isolation, sample port control, and flow-metering circuits in HVAC, refrigeration, and industrial process systems.

Key Features

• Straight-pattern body for direct inline installation
• 3000 psi maximum working pressure rating
• 1/8 inch pipe connection size for compact plumbing runs
• Precise needle-tip metering for accurate flow throttling and shutoff
• Lightweight at 0.3 pounds, suitable for tight or overhead installations

Compatibility

Designed as an OEM-style replacement or new-installation needle valve for 1/8 inch pipe systems requiring inline flow control at pressures up to 3000 psi.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified technician familiar with high-pressure piping systems. Depressurize and isolate the system completely before removing or installing any valve. Apply thread sealant or PTFE tape to pipe threads per the applicable IPC or IFGC requirements for the fluid or gas being handled. Do not exceed the 3000 psi maximum working pressure rating during service or testing.
