Parker 8A-PR6-VT-SS Plug Valve 3000 Psi 1/2 Inch 316 Ss

Product Description

The PARKER 8A-PR6-VT-SS is a 1/2 inch inline instrumentation plug valve rated for 3,000 psi working pressure. Built from 316 stainless steel with a Viton seal, this one-way valve is engineered for demanding instrumentation and process piping applications where corrosion resistance and tight shutoff are critical. A wedge-style handle provides quick quarter-turn actuation. The valve conforms to ANSI/ASME B1.20.1 thread standards, making it a direct fit for standard NPT pipe connections. It is well suited for hydraulic, chemical, and instrumentation systems requiring reliable flow isolation at elevated pressures.

This valve is used in industrial instrumentation and process control lines where pipe size is 1/2 inch and system pressure reaches up to 3,000 psi. Typical installations include high-pressure hydraulic panels, chemical injection systems, and instrumentation manifolds in commercial and industrial settings. The 316 stainless steel body handles corrosive media, and the Viton seal resists a wide range of chemicals and elevated temperatures. Installation is performed by licensed pipefitters, mechanical contractors, or instrumentation technicians.

Key Features

• Viton seal provides chemical and temperature resistance
• Wedge handle enables fast quarter-turn shutoff actuation
• Inline one-way configuration for straightforward in-line installation
• Conforms to ANSI/ASME B1.20.1 thread standards for standard NPT fitment

Compatibility

Designed as an OEM-style inline instrumentation plug valve for 1/2 inch NPT pipe connections in systems rated up to 3,000 psi WOG.

Installation Notes

Installation should be performed by a licensed pipefitter or instrumentation technician. Depressurize and isolate the line completely before removing or installing any valve. Apply appropriate thread sealant compatible with the process media to NPT threads per ANSI/ASME B1.20.1 requirements. Verify Viton seal compatibility with the specific process fluid and temperature range before commissioning.
