Watts 547100 Full Port Brass Ball Valve 1/4 Inch 600 Psi

Product Description

The WATTS 547100 is a 1/4-inch IPS 2-piece full port brass ball valve rated to 600 psi, designed for commercial and industrial fluid and gas control applications. It features a bottom-loaded blowout-proof stem for enhanced safety under pressure, a virgin PTFE seat for reliable sealing, and a chrome-plated brass ball for smooth, corrosion-resistant operation. The valve includes an adjustable stem packing gland and stem packing nut, allowing field adjustment to maintain a leak-tight seal. A steel lever handle provides positive quarter-turn shutoff. Licensed plumbers and pipefitters install this valve in systems handling water, oil, and gas service.

This valve is suited for commercial plumbing, industrial process piping, and mechanical systems where a compact, full-bore shutoff is required on 1/4-inch IPS lines. The 2-piece body design allows for in-line maintenance and seat inspection without removing the valve from the line. Full port construction minimizes pressure drop, making it appropriate for flow-critical applications across a broad range of liquid and gas media.

Key Features

• Bottom-loaded blowout-proof stem for safe operation under rated pressure
• Virgin PTFE seat and thrust washer for low-friction, leak-resistant sealing
• Chrome-plated brass ball for corrosion resistance and long service life
• Adjustable stem packing gland and nut allow field maintenance without valve removal

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 1/4-inch IPS threaded commercial and industrial piping systems handling water, oil, or gas service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code. Shut off the system and relieve all line pressure before installation or service. Use appropriate thread sealant or PTFE tape on IPS threads per the service medium requirements. Do not exceed the rated working pressure of 600 psi.
