The connection methods of electric actuated butterfly valve mainly include: flange connection and wafer connection; the sealing of electric actuated butterfly valve mainly includes: hard seal and soft seal. The electric actuated butterfly valve controls the switch to close through the electric actuator. It can be used as the blocking valve, throttle valve and check valve of pipeline system. With a manual control device, if there is a problem with the actuator, the switch of the valve body can be controlled by the manual device to close, so as not to affect the working conditions.
After the electric butterfly valve is installed and debugged by the regulating type electric actuator and the valve stem; electric energy is used as the driving force to drive the butterfly valve plate to make a partial reverse rotation movement. Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. The pneumatic butterfly valve is opened and closed with a circular butterfly plate that rotates with the valve stem.
The electric actuated butterfly valve receives the signal of the industrial automation control system to accurately control the opening and closing degree of valve, so as to achieve the adjustment and control of different required parameters such as flow, temperature, pressure. Pneumatic valves that have been switched are mainly used as shut-off valves, which can be used as switching and regulating applications. Nowadays, butterfly valves are used more and more in high-pressure large and medium-diameter pipelines.
As a component used to realize the on-off and flow control of the pipeline system, the electric butterfly valve is more and more widely used in practical applications with its excellent quality and performance!
