butterfly valves are flexibility and ease
There is a wide range and variety of Butterfly Valves available on the industrial market today with the best type by far being those configured for pneumatic control. These disks actively make use of an interactive gearbox and receive a signal from the valve operator for both opening and closing the electric ball valve. Flexibility and ease of use are the main advantages to this type of Butterfly Valve as it allows the option of single or double actuation by the valve operator. With single actuation, a fail safe is vital because in the event of a power loss the valve will still be able to be closed securely. Double action valves, which do not loaded with a spring, require signals each time they are opened or closed by the valve operator.
