Butterfly valve with actuator for more productive operations

butterfly valve with actuator [butterfly valve with actuator]

butterfly valve with actuator and switchbox

The butterfly valve with actuator is an efficient tool for automating any industrial process. The wide range of options, materials and configurations enable the butterfly valve to be controlled by a button and monitored live. The two common valve actuators are pneumatic and electric actuators. Actuators mounted on the butterfly valves are known as ‘rotary actuators’.

After the butterfly valve with actuator is assembled (with either the pneumatic or electric actuator), air or electricity is supplied to the actuator. The valve rotates to 90⁰ or for a quarter turn to open or close the valve. Other specific applications are possible by opening the valve at fixed points of 10⁰, 20⁰, 40⁰ and 45⁰.

The butterfly valve with actuator eliminates the need for an operator to stay near the valve and operate the valve manually. The operator can now control the movement of the valve remotely, from the control room.

The following accessories enhance the use of the butterfly valve with actuators

The switch box informs the operator when the valve is open or closed.
The electro-pneumatic positioner controls the valve using a 4-20mA signal.
The Namur solenoid valve controls the air supply with an electrical signal.
The spring return function (in electric and pneumatic actuators) or the battery back-up feature (in electric actuators), ensures a fail-safe operation.
The enclosure helps fulfil the ATEX requirements
Quick exhaust valve
Air filter regulator
Throttle plate
Needle valve
