Parker 2F-PR4-VT-B Plug Valve 3000 Psi 1/8 Inch Brass Fnpt

Product Description

The PARKER 2F-PR4-VT-B is a brass inline instrumentation plug valve rated for 3,000 psi WOG service. It features female NPT connections on both ends and a Viton seal for compatibility with a range of process fluids and gases. The wedge handle provides positive shutoff in a single quarter-turn motion. This valve is designed for use in instrumentation lines, process control circuits, and test point isolation where a compact, high-pressure shutoff is required. Installation is typically performed by instrumentation technicians, industrial pipefitters, or licensed plumbers working on high-pressure systems.

This plug valve is suited for inline one-way flow control in industrial instrumentation and process piping applications. The 1/8 inch pipe size and FNPT x FNPT end connections make it a straightforward threaded installation in tight-space instrument manifolds, gauge isolation, and sample point configurations. Its brass body holds up well in dry gas and non-corrosive fluid service at elevated pressures up to 3,000 psi.

Key Features

• 3,000 psi WOG pressure rating for demanding instrumentation service
• Brass body construction provides corrosion resistance in non-corrosive media
• Viton seal for broad chemical compatibility across process fluids and gases
• FNPT x FNPT end connections conform to ANSI/ASME B1.20.1 thread standards
• Wedge handle delivers quick, positive quarter-turn shutoff
• Compact inline design suited for tight instrumentation manifold installations

Compatibility

Designed as an OEM-style instrumentation plug valve for 1/8 inch female NPT threaded process and instrumentation piping systems operating within the rated pressure and temperature limits of the valve body and seal materials.

Installation Notes

Installation should be performed by a qualified pipefitter, instrumentation technician, or licensed plumber in accordance with applicable codes including ANSI/ASME B31.1 or B31.3 as appropriate. Depressurize and isolate the system completely before removing or installing any valve. Apply thread sealant or PTFE tape to male NPT threads per standard practice, avoiding contamination of the valve bore. Do not exceed the rated working pressure of 3,000 psi.
