Parker 8M-PR6-VT-SS Plug Valve 3000 Psi 1/2 in Mnpt Ss

Product Description

The PARKER 8M-PR6-VT-SS is a 1/2 inch inline instrumentation plug valve rated for 3,000 psi WOG service. The body is machined from 316 stainless steel and uses a Viton seal, making it suited for corrosive media, process instrumentation lines, and high-pressure fluid systems. The valve operates as a one-way shutoff with a wedge handle for positive open and closed indication. Male NPT connections on both ends conform to ANSI/ASME B1.20.1 thread standards. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers for this type of valve in industrial and commercial settings.

This valve is intended for inline instrumentation applications where a compact, high-pressure shutoff is required. Typical installations include process control lines, hydraulic instrument root valves, and chemical or petrochemical distribution headers. The 316 stainless steel body provides resistance to chloride and acidic environments. The MNPT x MNPT end connections allow direct threaded installation into existing pipe runs without additional fittings. The wedge handle design keeps the assembly profile low in tight panel or manifold configurations.

Key Features

• 3,000 psi WOG working pressure rating for high-pressure instrumentation service
• 316 stainless steel body for corrosion resistance in aggressive media
• Viton seal compatible with a wide range of chemicals and elevated temperatures
• MNPT x MNPT end connections conforming to ANSI/ASME B1.20.1
• Wedge handle provides clear visual indication of valve position
• Compact inline design suited for panel boards and instrument manifolds

Compatibility

Designed as an OEM-style instrumentation plug valve for 1/2 inch MNPT threaded pipe systems operating at up to 3,000 psi WOG in industrial or commercial instrumentation applications.

Installation Notes

Installation should be performed by a licensed pipefitter or instrumentation technician following applicable ASME and local piping codes. Depressurize and isolate the line completely before removing any existing valve or fitting. Apply appropriate thread sealant rated for the service media to all MNPT connections and tighten to the fitting manufacturer's recommended practice without over-torquing. Verify valve orientation and confirm handle position before returning the system to service.
