Parker 6M-V6LN-SS Needle Valve 3/8 Inch Mnpt 5000 Psi Ss

Product Description

The PARKER 6M-V6LN-SS is a straight needle valve designed for precise flow control in high-pressure fluid and gas systems. Built from 316 stainless steel, it handles maximum working pressures up to 5000 psi, making it suitable for demanding industrial and mechanical service applications. The valve features male NPT connections on both ends in a 3/8 inch pipe size, allowing straightforward inline installation. Licensed plumbers, pipefitters, and HVAC technicians working on high-pressure lines will find this valve a reliable choice for throttling and shutoff service.

This needle valve is used in applications where precise flow regulation or positive shutoff is required under high-pressure conditions. Common install scenarios include hydraulic systems, instrumentation lines, refrigeration service ports, compressed gas systems, and process piping. The straight-body configuration keeps the flow path aligned with the pipe run, simplifying installation in tight or linear plumbing layouts. Its 316 stainless construction makes it appropriate for corrosive media and environments where carbon steel fittings are not suitable.

Key Features

• 316 stainless steel construction for corrosion resistance in harsh service environments
• Maximum working pressure of 5000 psi for high-pressure fluid and gas applications
• Straight-body design with MNPT x MNPT connections for inline installation
• 3/8 inch pipe size for compatibility with standard NPT piping and fittings
• Needle-style trim provides accurate flow throttling and positive shutoff

Compatibility

Designed as an OEM-style replacement or direct-fit component for high-pressure inline applications using 3/8 inch male NPT connections in stainless steel piping systems.

Installation Notes

Installation of high-pressure needle valves should be performed by a licensed pipefitter or qualified mechanic familiar with the applicable system pressure ratings. Depressurize and isolate the line completely before removing any existing valve or fitting. Apply thread sealant rated for the working pressure and media type to the MNPT threads before assembly. Verify the installed torque and pressure ratings do not exceed the valve specifications before returning the system to service.
