Flanged Stainless Steel Ball Salve Matched with PTAT Electric Actuator

1. The Quarter-turn Electric Actuator(angle <360 degrees) is suitable for butterfly valves, ball valves, plug valves, etc.
The rotation of the output shaft of the electric actuator is less than one week, that is, less than 360 degrees, usually 90 degrees to achieve the valve opening and closing process control. Such electric actuators are divided into direct connection type and base crank type according to different installation interface modes.

a) Direct connection: refers to the form in which the output shaft of the electric actuator is directly connected to the valve stem.

b) Base crank type: refers to the form in which the output shaft is connected to the valve stem through the crank.

2. Multi-turn electric actuator (angle > 360 degrees) is suitable for gate valves, globe valves, etc.
The rotation of the output shaft of the electric actuator is greater than one week, that is, greater than 360 degrees. Generally, multiple turns are required to control the opening and closing process of the valve.

3. Linear Modulating Actuator (linear motion) is suitable for single seat control valves, two-seat control valves, etc.
The movement of the output shaft of the electric actuator is linear, not in the form of rotation.
