What Is a Handle Groove Butterfly Valve?
A Handle groove butterfly valve is a quarter-turn valve featuring grooved-end connections and a manual lever handle. Its design allows for quick assembly into grooved pipe systems without the need for flanged or welded connections, significantly reducing labor time and complexity.
Designed for flow isolation or throttling, this valve provides:
- Compact structure for tight spaces
- Tool-free adjustment via multi-position handle lock
- Low torque operation for user convenience
- Bidirectional sealing with tight shut-off performance
- Quick disassembly and replacement for service and upgrades
It is especially popular in HVAC systems, fire sprinkler pipelines, and industrial circulation loops where shut-off and modulation control are frequently required.
Optimized Flow Control for Demanding Applications
The design of the valve disc and seat delivers excellent butterfly control valve flow characteristic performance. Whether fully open, closed, or modulating in between, the valve maintains consistent pressure drop and minimal flow turbulence.
This enables system designers and facility engineers to achieve:
- Accurate flow regulation
- Reduced system noise and vibration
- Improved energy efficiency
- Extended equipment lifespan
Il butterfly control valve flow characteristic makes this product an ideal fit for applications where manual control and precision must go hand-in-hand, such as chilled water systems, fire loops, and ventilation ducting.
