Parker 8A-PR6-VT-B Plug Valve 3000 Psi 1/2 Inch Brass

Product Description

The PARKER 8A-PR6-VT-B is a brass inline instrumentation plug valve rated for 3,000 psi WOG service. It features a wedge handle design and a Viton seal, making it suitable for applications where chemical resistance and reliable shutoff are required. The one-way flow path and compact inline body make this valve a practical choice for instrumentation tubing and piping systems where space and pressure integrity are priorities. Licensed pipefitters and instrumentation technicians typically install this type of valve in process control, hydraulic, or high-pressure fluid lines. The 1/2 inch pipe connection conforms to ANSI/ASME B1.20.1 thread standards.

This valve is designed for use in instrumentation and process piping systems operating at pressures up to 3,000 psi WOG. It fits inline configurations in both industrial and commercial settings where a manually operated quarter-turn shutoff is needed. The brass body handles a broad range of fluid media, and the Viton seal adds resistance to fuels, oils, and many chemical fluids. Typical installation scenarios include hydraulic test panels, gauge isolation, sampling ports, and high-pressure instrument connections.

Key Features

• 3,000 psi WOG pressure rating for high-pressure instrumentation service
• Brass body construction for corrosion resistance across a wide range of media
• Viton seal provides chemical and fuel resistance for demanding fluid environments
• Wedge handle design allows positive manual shutoff with tactile confirmation
• Inline one-way configuration simplifies installation in tight instrumentation runs
• 1/2 inch pipe connection conforming to ANSI/ASME B1.20.1 thread standard

Compatibility

Designed as an OEM-style instrumentation plug valve for 1/2 inch pipe systems requiring a 3,000 psi WOG rated inline shutoff valve with Viton sealing.

Installation Notes

Installation should be performed by a licensed pipefitter or instrumentation technician familiar with high-pressure fluid systems. Depressurize and isolate the line completely before removing any existing valve or fitting. Apply appropriate thread sealant in compliance with ANSI/ASME B1.20.1 requirements and do not overtighten the threaded connection. Verify system pressure rating compatibility before returning the line to service.
