Description
The Bray Commercial 310400-11010390 is a 4-inch lugged-style butterfly valve with a bare stem configuration, engineered for reliable flow isolation and regulation in commercial HVAC, mechanical, and industrial piping systems. Bray Commercial is a trusted name in valve technology, delivering precision-crafted products built to meet the rigorous demands of building mechanical systems.
Lugged Body Design
The lugged body configuration enables this butterfly valve to serve as a dead-end service valve — ideal for systems where one side of the pipeline must be isolated and disconnected without disturbing the opposite side. This design provides greater installation flexibility over wafer-style valves and is fully compatible with standard ANSI/ASME flange bolt patterns.
Bare Stem Configuration
The bare stem design allows this valve to be paired with a wide range of manual handles, gear operators, or electric and pneumatic actuators — giving engineers and contractors the flexibility to configure the valve for their specific application. This versatility makes the 310400-11010390 a dependable choice for both manual and automated system designs.
