1, a remote control of automatic butterfly valve, at the same time with the characteristics of the flange butterfly valve, butterfly valve can be equipped with a wide diameter;
2. Power supply is the driving energy of butterfly valve. It has a wide range of power sources, wide application scope, saving human resources and working efficiency.
3, easy to operate, easy to meet a variety of control requirements, matching different actuators can be achieved, signal feedback, flow regulation, explosion-proof and other functions;
4, can realize the miniaturization, can realize the mechanical self-locking, can change different sealing ring, meet different working conditions.
Using the actuator input 0-10 ma standard signal, the electric unit drives the gear turbine worm Angle torque to drive the disc rotation. When the valve is in the fully open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics.
Butterfly valve elastic seal and metal seal two types of sealing. Elastic seal valve, sealing ring can be embedded in the valve body or attached to the butterfly plate around, the valve with metal seal is generally longer than the elastic seal valve life, but it is difficult to achieve complete sealing. Metal seal can adapt to higher working temperature, elastic seal is limited by the temperature of the defect, if the demand for flanged butterfly valve as flow control, the main is to choose the correct size and type of valve.
