Anvil 4301659020 Full Port Ball Valve 3/8 Inch Fnpt

Product Description

The ANVIL 4301659020 is a 3-piece, full port manual ball valve designed for reliable shutoff and flow control in plumbing, HVAC, and industrial piping systems. The body, trim, and finish are all 316 stainless steel, making this valve well-suited for corrosive or high-purity service environments. PTFE (polytetrafluoroethylene) seats and seals provide low-friction operation and chemical resistance across a wide range of media. The locking lever handle prevents accidental actuation, an important feature in commercial and industrial installations where inadvertent shutoff or opening can disrupt service.

This valve is used in residential and commercial piping systems where a 3/8 inch female NPT connection is required on both ends. Common applications include water service lines, chemical distribution, compressed air, and hydronic systems. The full port design minimizes pressure drop across the valve, maintaining system flow rates without restriction. Licensed plumbers and pipefitters typically specify this valve where corrosion resistance and a positive locking shutoff are priorities.

Key Features

• 316 stainless steel body, trim, and finish for corrosion resistance in demanding service environments
• Full port bore minimizes pressure drop and maintains full flow capacity
• PTFE seats and seals provide chemical resistance and low-friction quarter-turn operation
• Locking lever handle prevents unintended valve actuation
• FNPT x FNPT end connections on both ends for standard threaded pipe assembly
• 3-piece construction allows in-line service and seat replacement without removing the valve body

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 3/8 inch female NPT threaded piping systems in plumbing, HVAC, and light industrial applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the system completely before installing or replacing any valve. Apply thread sealant or PTFE tape to male NPT threads per standard practice, and do not overtighten threaded connections. Verify that the valve handle is in the closed position before restoring system pressure.
