Because some customers mentioned flange butterfly valves, we also popularize knowledge for other flange buyers. This is a kind of remote control, which provides convenience for users in space. The power supply is the driving energy of the flange butterfly valve. It has a wide range of power sources and a wide range of applications, saving human resources and working efficiency; The flange butterfly valve is easy to operate and can easily meet various control requirements. It can be realized by selecting different actuators, including signal feedback, flow regulation, explosion-proof and other functions; In addition, the flange butterfly valve can realize ultra miniaturization, realize mechanical self-locking, and change different sealing rings to meet different working conditions.
Working principle of flange butterfly valve: use the actuator to input a standard signal of 0-10 Ma, and the motor group drives the gear, worm and worm angular 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 passing through the valve is very small, so it has good flow control characteristics. Flange butterfly valve has two sealing types: elastic seal and metal seal. For elastic seal valves, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate. The valve with metal seal generally has a longer service life than the flange butterfly valve with elastic seal, but it is difficult to achieve complete sealing. Metal seal can adapt to higher working temperature, while elastic seal has the defect of being limited by temperature. If flange butterfly valve is required to be used as flow control, the main thing is to correctly select the size and type of valve.
