Parker 2M-V4LN-B Needle Valve 1/8 Inch Mnpt Brass 3000 Psi

Product Description

The PARKER 2M-V4LN-B is a straight-pattern needle valve designed for precise flow control in high-pressure fluid and gas systems. It features a brass body with a polytetrafluoroethylene (PTFE) seal, a round handle for manual adjustment, and male NPT connections on both ends. The valve is rated to 3,000 psi maximum working pressure, making it suitable for demanding hydraulic, pneumatic, and instrumentation applications. At 1.62 inches overall length and 3.06 inches overall height, it is a compact unit. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers for this type of valve.

This needle valve is sized for 1/8 inch pipe and uses MNPT x MNPT end connections, making it a straightforward threaded installation into existing pipe systems. It is well suited for residential and light commercial plumbing, hydraulic test panels, instrumentation tubing circuits, and process control lines where accurate flow throttling is required. The PTFE seal material provides good chemical resistance across a range of media including water, air, and many common process fluids.

Key Features

• Straight-pattern body for in-line flow control installations
• Brass body construction for corrosion resistance in fluid and gas service
• PTFE seal for chemical compatibility and reliable low-leak performance
• Rated to 3,000 psi maximum working pressure
• Round handle for manual flow adjustment without additional tools
• MNPT x MNPT end connections for direct threaded pipe installation

Compatibility

Designed as an OEM-style replacement or new-installation needle valve for 1/8 inch MNPT threaded pipe systems operating at up to 3,000 psi.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Depressurize and isolate the system fully before removing any existing valve or fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before installation and tighten to hand-snug plus a moderate wrench turn — do not overtighten, as brass fittings can crack. Verify system pressure rating does not exceed the 3,000 psi maximum working pressure of this valve before returning the system to service.
