Parker 8A-V8LN-B Straight Needle Valve 3000 Psi 1/2 in

Product Description

The PARKER 8A-V8LN-B is a straight-pattern needle valve designed for precise flow control in high-pressure piping systems. Rated to 3000 psi maximum working pressure, this valve provides reliable shutoff and throttling for hydraulic, pneumatic, and industrial fluid lines. It accepts 1/2 inch pipe connections and is suited for applications where fine flow regulation is required. Plumbers, pipefitters, and industrial maintenance technicians commonly specify this type of valve in systems that demand accurate flow metering under sustained pressure loads.

This straight needle valve is used in residential and commercial mechanical systems where controlled fluid flow and tight shutoff are critical. Typical installation scenarios include instrumentation lines, hydraulic test stands, compressed air circuits, and process piping. The 1/2 inch pipe size makes it compatible with standard half-inch threaded pipe runs commonly found in industrial and mechanical trade work.

Key Features

• Straight-pattern body style for in-line installation without flow direction change
• 3000 psi maximum working pressure rating for high-pressure service
• 1/2 inch pipe size fits standard NPT threaded connections
• Needle-type stem provides fine throttling and precise flow control
• Compact form factor suited to tight mechanical spaces

Compatibility

Designed as an OEM-style replacement or direct-install straight needle valve for 1/2 inch threaded pipe systems rated to 3000 psi.

Installation Notes

Installation should be performed by a licensed pipefitter or qualified mechanic familiar with high-pressure fluid systems. Depressurize and isolate the system fully before removing or installing any valve. Apply appropriate thread sealant to NPT connections per system requirements and applicable plumbing codes. Do not exceed the 3000 psi maximum working pressure rating under any operating condition.
