The BONOMI 511L34 is a 3/4-inch brass exhaust ball valve designed for exhaust service applications in plumbing and industrial piping systems. The full brass body construction provides durability in moderate-pressure exhaust lines, and the ball valve mechanism delivers a quarter-turn shutoff for fast, reliable flow control. This valve ships as a single unit and is typically installed by licensed plumbers or mechanical contractors working on exhaust or vent piping assemblies.
The 511L34 is suited for exhaust service in residential and light commercial piping systems where a compact, brass-bodied ball valve is required. Its 3/4-inch port size fits standard 3/4-inch pipe connections, making it a practical choice for inline exhaust control on gas or fluid exhaust lines. It is sold as a single valve and is intended for installations where a manual quarter-turn shutoff is specified.
Designed as an OEM-style replacement or new-installation valve for 3/4-inch exhaust service piping systems in residential and light commercial applications.
Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local plumbing codes. Shut off system pressure and depressurize the line completely before removing or installing the valve. Verify thread type and pipe schedule compatibility before making connections. Do not exceed the valve's rated pressure and temperature limits for the intended service.
