QT series of electrical units for partial rotation of valves are suitable for controlling butterfly valve, ball valve, plug valve, they can make such valves rotate at 90°.The product has the following features: Small volume, light weight, high efficiency, high reliability, high protection property and low noises etc. The unit can be operated on site, and controlledin long distance. And it can be widely used in various industries, such as petroleum, chemical industry, power plant, water treatment, and paper making industry etc.
The company has developed new intelligent actuator; selection function is increased on the basis of switch type actuator, which increased more selection space for users with different demands.
1.Small volume, light weight, and high protective level.
2.Excellent mechanical driving system, stable performance.
3.Self error correction of the power supply’s phase sequence and the function of phase disconnection warning protection.
4.Self-regulation function, the machine can receive and feedback 4-20 mA current signals to the computer, DCS and PLC, both channels of input/ output signals adopt photoelectricity isolation (can withstand 2000 V surge voltage).
5.Non-invasion design, free-opening commissioning, setting with the remote control, and achieve man-machine conversation with the window.
6.Full-Chinese characters display, provide good user interface.
7.Self-diagnosis technology of operation failures.
8.Over-heat protection function of the motor.
9.Using micro- electronic technique, computer technology, IR remote technology, magnetic-control switch technology, LCD digital display technology to substitute
traditional control methods.
10.Bus control of operational network, the mechanism can achieve current popular various on-site bus functions by increasing different bus interfaces, such as Profibus etc.
11.The power supply can adopt different methods, such as three-phase three-wire system, three-phase four-wire system, and single phase etc.
12.The connection can adopt outgoing method with the aviation plug.
13.Installation method: Installed at any position at 360 °(partial rotation).
14.The locking unit can position the magnetic knob to position of some gear, thus can avoid accidents caused by misoperation of non-specialized person.
