Electric Butterfly Valve

The  electric  butterfly valve adopts an integrated structure, which can be controlled by connecting to a 220VAC power supply. It can also be equipped with a control module to input control signals (4-20mADC or 1-5VDC) for regulation and control.
Electric Butterfly Valves have strong functions, small size, lightweight and pleasant, reliable performance, simple matching, and large flow capacity. For room temperature and clean media, valve plates with soft seals (rubber rings, PTFE rings) can be used to reduce leakage (up to 0.01%). For high temperature and high pressure conditions, a three eccentric hard seal valve body can be selected. Please indicate it when placing an order. It is widely used in industrial process automatic control systems in industries such as food, environmental protection, light industry, petroleum, chemical, teaching equipment, papermaking, and power.
Electric Butterfly Valves have a simple structure, small size, and light weight, consisting of only a few components. And it only needs to rotate 90 degrees to quickly open and close, with simple operation, and the valve has good liquid control characteristics. When the Electric Butterfly Valve is in the open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body, so the pressure generated through the valve is very small, which has good flow control performance. Electric butterfly valves have two sealing models: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate. Electric  butterfly valves are suitable for opening, closing, or regulating flow in pure pipelines such as food, beverage, pharmaceutical, and chemical industries, as well as in industrial environmental protection, water treatment, high-rise buildings, HVAC, fire protection, and water supply and drainage pipelines.
It can be widely used in industrial process automatic control systems in industries such as food, environmental protection, light industry, petroleum, chemical, teaching equipment, papermaking, electricity, etc. Technical parameters and performance Valve body: nominal diameter: DN50-400mm nominal pressure: PN1.6, 4.0, 6.4MPa Connection form: flange type according to JB/T78-59 JB79-59 Clamp on flange Connection material: HT200 ZG25 ZG1Gr18Ni9Ti ZGOCr18Ni12Mo2Ti Upper valve cover: room temperature type: -20~+200 ℃ Heat dissipation type:+200~+450 ℃ Capping form: bolt compression type Packing: V-shaped polytetrafluoroethylene, flexible graphite, asbestos braided packing lined with rubber, lined with PTFE Sealing material: stainless steel, rubber, PTFE Valve internal components: Valve core form: valve plate Flow characteristics: equal percentage or linear characteristic material.
