Parker 8Z-V8LN-SS Needle Valve 1/2 in Compression Stainless

Product Description

The PARKER 8Z-V8LN-SS is a straight-pattern needle valve designed for precise flow control in high-pressure fluid and gas systems. Built with a 316 stainless steel body and a polytetrafluoroethylene (PTFE) seal, it handles working pressures up to 5,000 psi. The compression x compression end connections accept 1/2 inch tubing on both sides, making installation straightforward without threading or soldering. The round handle provides positive manual control. This valve is installed by licensed plumbers, pipefitters, and instrumentation technicians working in industrial, process, or high-purity fluid systems.

This valve is suited for straight-line installation in high-pressure hydraulic, pneumatic, chemical, or instrumentation tubing runs. The compression fittings on both ends allow connection to standard 1/2 inch tubing. The 316 stainless steel body offers corrosion resistance in aggressive media environments, including saltwater, mild acids, and process chemicals. At 3.06 inches overall length and 4.18 inches overall height, it fits in compact panel or manifold installations where space is limited.

Key Features

• 316 stainless steel body for corrosion resistance in demanding process environments
• PTFE seal compatible with a wide range of fluids and gases
• 5,000 psi maximum working pressure rating
• Compression x compression end connections for 1/2 inch tubing — no threading required
• Straight-pattern flow path simplifies inline installation
• Round handle for easy manual actuation and positive shutoff

Compatibility

Designed as an OEM-style inline needle valve for high-pressure instrumentation, hydraulic, and process piping systems using 1/2 inch compression tubing connections.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician. Depressurize and isolate the line completely before removing or installing the valve. Compression fittings require proper ferrule seating — do not overtighten, as this can damage the tubing or ferrule and cause leaks. Verify that system media and operating pressure are compatible with stainless steel and PTFE before placing the valve in service.
