Optional Electric Actuator
1.The small butterfly valve has a large market share, with a sophisticated appearance, an economical price, and multiple protection functions such as electrical limit, mechanical limit, overheat protection, and dehumidification protection. It is AC415V, 380V, 240V, 220V, 110V,. DC24V AC as the driving power supply, with 4-20Ma current signal or 0-10VDC voltage signal as the control signal, which can make the valve move to the required position, realize automatic control, and the maximum output torque 6000Nm. Exquisite, compact, beautiful and generous, the control methods include switch type, passive contact type, proportional type, and intelligent adjustment type.
2.The QT type valve electric device has a larger volume than a fine and small size, and the price is slightly higher than that of a small size. However, the QT model has increased the over-torque protection function, and at the same time increased a variety of control signals, the customer's choice is more extensive. The clutch device is added, and the electric, power/manual state can be switched through the clutch. It can be a bus type, and a variety of communication protocols are optional. Optional torque: 50-2500Nm. It can be installed directly and on the base. When used as a flameproof type at the same time, the flameproof grade is also higher than that of the fine and small.
3.The SD model has a variety of voltage optional servo motors, with over-torque protection function. When the power signal is lost, it can remain in the original position before the power loss or signal loss, and can output and output the alarm contact, and can display the valve position. It can realize the mutual switching between remote and local operation control, and the local operation part has protective measures to prevent misoperation. Optional torque: 100-35000Nm.
4.Q models are mostly 380V power supply, with clutch device, electric/manual state can be passed, clutch switching, over torque function, large volume, large output torque, large diameter valve can be equipped, optional torque: 100-165000Nm.
