The PARKER 8M-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, this valve handles working pressures up to 5,000 psi. The round handle provides reliable manual actuation. With male NPT connections on both ends, it threads directly into standard pipe fittings without adapters. Licensed plumbers, pipefitters, and industrial technicians install this type of valve in process piping, instrumentation lines, and hydraulic systems where tight shutoff and corrosion resistance are required.
This valve is suited for residential, commercial, and light industrial applications where a compact, corrosion-resistant shutoff or throttling point is needed. The straight-body configuration works in inline installations with 1/2 inch NPT threaded pipe. The stainless steel construction and PTFE sealing make it appropriate for use with water, steam, oils, and many aggressive media. It fits into instrument manifolds, test ports, and isolation service points commonly found in HVAC, plumbing, and process control systems.
Designed as an OEM-style replacement or new-installation needle valve for 1/2 inch male NPT threaded pipe systems requiring stainless steel construction and high-pressure capability up to 5,000 psi.
Installation is performed by licensed plumbers or qualified pipefitters. Depressurize and isolate the affected line completely before removing or installing any valve. Apply thread sealant or PTFE tape to NPT threads in accordance with applicable plumbing and piping codes such as ASME B31.1 or IPC. Do not exceed the rated working pressure of 5,000 psi in service.
