DN40 to DN1200 Headless Double Flange Butterfly Valve Cast Iron
Butterfly valves are often automated with pneumatic or electric actuators. This allows remote operation for a variety of reasons: savings in labor, plant safety, product quality assurance, and automatic sequencing, to name a few. The choice of actuator type depends on many factors, including availability of air supply, cycling requirements, condition of the environment, compatibility with the type of control operation, and cost. Positioners may be mounted on these valves if flow control is required.
