Butterfly Control Valve
High-performance butterfly control valves featuring a double eccentric disc design for precise flow regulation, reduced torque, and reliable shut-off in demanding industrial applications.
Advanced Butterfly Control Valve Solutions
Engineered for precise flow control and long service life, our butterfly control valves feature a double eccentric cammed disc design that minimizes seat wear and operating torque. The one-piece straight-through body ensures a low pressure drop, while the splined shaft eliminates dead band and transmission loss. Available with wafer, lugged, and flanged end connections, these valves offer equal percentage, linear, and quick-open flow characteristics. With clamped, self-aligned seats delivering up to ANSI Class VI shut-off, they integrate seamlessly with pneumatic spring-cylinder rotary actuators for intelligent and reliable process automation.
