Features and applications
Explosion-proof electric actuators
◎ standard switch type (type B)
The opening and closing operation of the valve is realized by the switch circuit, and a set of active contact signals are outputted at the same time, indicating that the valve position is in a fully open or fully closed state.
◎ Passive contact type (S type)
The switch circuit is used to open and close the valve, and a set of passive contact signals are outputted to indicate that the valve position is fully open or fully closed.
◎With position signal type (K type)
The valve is opened and closed by the switch circuit, and the current signal corresponding to the valve opening and closing angle is output.
◎ opening signal type (R type)
The valve opening angle is controlled by the switch circuit, and the potentiometer outputs a resistance signal corresponding to the position of the valve opening.
◎Intelligent adjustment type (A type)
The regulation and control are realized by receiving a standard signal of 4-20 mA.DC, 0-10 V.DC or 1-5 V.DC output from a computer or industrial instrument, and a standard feedback signal of 4-20 mA.DC is output.
