Parker 6F-V8LN-SS Straight Needle Valve 3/8 in Fnpt 5000 Psi

Product Description

The PARKER 6F-V8LN-SS is a straight needle valve designed for precise flow control in high-pressure fluid and gas systems. Constructed from 316 stainless steel, this valve handles a maximum working pressure of 5,000 psi, making it well-suited for demanding industrial and mechanical service environments. The 3/8 inch FNPT x FNPT end connections allow for direct inline installation into standard threaded pipe runs. Licensed plumbers, pipefitters, and mechanical contractors typically install this type of valve where fine throttling control and corrosion resistance are required in a compact, straight-body configuration.

This needle valve is appropriate for use in hydraulic, pneumatic, instrumentation, and process piping systems where high-pressure shutoff or flow regulation is needed. Its 316 stainless steel construction makes it a strong fit for corrosive media, chemical processing lines, offshore or marine environments, and food-grade or sanitary-adjacent applications where material compatibility is critical. The straight body style simplifies inline installation without requiring pipe offset or angled fitting adapters.

Key Features

• Straight body configuration for direct inline pipe installation
• Rated to 5,000 psi maximum working pressure for high-pressure service
• 316 stainless steel construction for corrosion resistance in aggressive media
• 3/8 inch FNPT x FNPT connections compatible with standard threaded pipe fittings
• Needle design provides precise, fine-tuned flow throttling control

Compatibility

Designed as an OEM-style inline needle valve for 3/8 inch FNPT threaded pipe systems operating at up to 5,000 psi, typical in hydraulic, pneumatic, and instrumentation applications requiring stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable mechanical and piping codes. Depressurize and isolate the system fully before removing any existing valve or fitting. Apply appropriate thread sealant rated for the intended media and pressure range to FNPT connections before makeup. Do not exceed the rated 5,000 psi maximum working pressure under any operating or test condition.
