Working principle of flange

flange working characteristics:

1, a remote control butterfly valve, at the same time with the characteristics of flange butterfly valve, can be equipped with a wide range of butterfly valve diameter;

2. The power supply is the driving energy of the butterfly valve, with a wide range of power sources, wide application range, saving human resources and working efficiency;

3, easy to operate, easy to meet a variety of control requirements, the choice of different actuators can be achieved, signal feedback, flow regulation, explosion-proof and other functions;

4, can achieve ultra-miniaturization, can achieve mechanical self-locking, can change different sealing ring, to meet different working conditions.
flange working principle:

uses the actuator to input a standard signal of 0-10 mA, and the motor unit drives the gear, turbine and worm angle torque to drive the disc plate to rotate. 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 good flow control characteristics.

butterfly valve has elastic seal and metal seal two types of sealing. Elastic sealing valve, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate, the use of metal sealing valve is generally longer than the elastic sealing valve life, but it is difficult to achieve a complete seal. Metal seal can adapt to higher working temperature, elastic seal is limited by the temperature of the defect, if the demand flange butterfly valve as a flow control use, the main is the correct choice of valve size and type.
