6、 Electric ventilation butterfly valveactuator

381RSeries electric actuator:

1The actuator is designed with a servo system (no need for additional servo amplifiers), just connect itDC4～20mA(orDC1～5V）Signal andAC220VA single-phase power supply is sufficient for operation. Equipped with internal wiring terminals, the wiring is extremely simple and convenient.
2Key components of the actuator─The controller adopts the most advanced hybrid integrated circuit, sealed and cast with resin, with a box shaped appearance, small volume, and high reliability.
3The feedback detection of the driving quantity adopts high-performance conductive plastic potentiometers with resolution<0.4%.
4Equipped with self diagnostic function, when a fault occurs, the indicator light on the controller will immediately emit an indication signal.
5The state selection switch can be used to set the cut-off signal when the valve core is in the fully open, fully closed, or self-locking state.
6The state selection switch can be used to set (forward and reverse actions).
7The state selection switch can be used to set the input signal to（DC4～20mAperhapsDC1～5V）.
8Adjusting the work zero point (starting point) and travel (ending point) is simple and easy.
9When there is a sudden power outage, it can ensure that the valve core is self-locking.
10Adopting synchronous belt transmission effectively reduces noise.
11Delay protection function, can implement state self-locking when rated load, can immediately start protection when a fault occurs, and can reverse operation to cancel delay protection.
