Two, electric butterfly valve type switch and intelligent butterfly valve to the practice of form a complete set of institutions, the DSR input control standard lights ( 4 ~ 20 madc or 1 ~ 5 VDC) And single-phase power supply can control operation, with strong function, small volume, light and pleasant, form a complete set of reliable performance, simple, large flow capacity, especially is suitable for medium is strong, including particle, fiber temper. At present, the valve is widely used in food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power, etc in the industrial control system. A, the body ( Electric butterfly Industrial Valves) Nominal size: 50 - 1200 mm nominal pressure: PN1. 0 site SEO optimization, 1. 6, 2. 5 mpa connection situation: flange according to JB/T78 - 59JB79- 59 the wafer flange connection material: HT200ZG25IZG1Cr18Ni9ZG0Cr17Ni12Mo2 lining ptfe metal hard seal medium temperature: room temperature type: - 20 oc ~ + 200 oc heat type: - Within 40 oc ~ + 450 oc, valve components ( Electric butterfly valve) Situation: valve core flow characteristics of valve plate: linear features or percentage of materials: HT200ZG25I1Cr18Ni9Ti lining rubber lining tetrafluoroethylene three, implementing agency ( Electric butterfly valve) Type: can choose QS series, series 3810, series DSR electronic angular travel agencies. Electric flanged butterfly valve is suitable for hvac and refrigeration industry, at the same time can also be used in industrial field, general services and water treatment. Advantage 1, convenient electric flanged butterfly valve opening and closing rapidly, energy saving, fluid resistance small, can often operation. 2, electric flanged butterfly valve has simple structure, small volume, light weight. 3, electric flanged butterfly valve can transport the mud, and the apertures least accumulated liquid. Four, electric flanged butterfly valve under low pressure, can achieve good sealing. 5, electric flanged butterfly valve regulating performance is good.
