Power of electric butterfly valve
Power of electric butterfly valve
Electric butterfly valve is one of the valve varieties commonly used in industrial pipeline. Butterfly valve small size, less material, light weight, larger diameter relative to other valves more economical and affordable. Pneumatic actuator can be quickly opened and closed by rotating 90°, easy to operate. At the same time, the valve has good fluid control characteristics. Butterfly valve is in the fully open position, butterfly plate thickness is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, when the open degree is about 15° to 70° between, and can be sensitive flow control, so large diameter flow regulation, butterfly valve has a greater advantage. Not suitable for process media with high particle and temperature.
The power of the electric butterfly valve is closely related to the caliber of the electric butterfly valve. The larger the caliber of the electric butterfly valve is, the greater its power will be. General electric butterfly valve power z small will be maintained at 15W. The power operating current of 15W electric butterfly valve is 0.25a。
Electric butterfly valve is an automatic valve system driven by power supply and an important executive unit in industrial automation control pipeline. The electric butterfly valve is composed of a one-piece electric actuator and a butterfly valve. Electric butterfly valve electric actuator output thrust, compared with pneumatic butterfly valve closing speed faster, more stable operation, small impact force. Electric butterfly valve is generally used in petrochemical industry, food, medicine, paper power, sewage treatment and other industrial pipelines. Electric butterfly valve is characterized by small driving torque, open and close more flexible, easy to operate.
Electric butterfly valve features
(1) double eccentric structure, with the sealing function of more and more tight, reliable sealing performance.
(2) the sealing auxiliary material is matched with stainless steel and nitrile oil resistant rubber, with long service life.
(3) the rubber sealing ring can be located on the valve body or on the butterfly plate. It can be applied to different media with different characteristics for users to choose.
(4) the butterfly plate adopts frame structure with high strength, large flow area and small flow resistance.
(5) overall baking paint can effectively prevent corrosion and can be used in different media as long as the sealing material of better sealing seat is better.
(6) the valve has a two-way sealing function, installation is not subject to the control of the flow of media, also not affected by the space position. Can be installed in any direction.
(7) small size, light weight, reliable performance, simple supporting equipment, large circulation capacity, especially suitable for the medium is relatively clean liquid and gas.
