Electric Butterfly Valve Overview: Electric butterfly valve with a "U" type stainless steel seal, the precision of the elastic ring and polished disc three-dimensional eccentric contact. It solves the defect that the traditional eccentric butterfly valve is still in sliding contact friction at the moment when the opening and closing is 0 ° ~ 10 °, so that the sealing surface of the butterfly valve can be separated at the moment of opening and the effect of closing the contact is sealed, thus prolonging the service life and sealing performance Good purpose. Therefore, it is widely applied to the pipeline of metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage corrosive media with medium temperature ≤550 ℃. It is the best device to regulate the flow and cut off the fluid. Electric butterfly valve features: 1, the butterfly valve structure is simple, compact, light weight, easy to install and remove, easy maintenance; 2, the butterfly valve with stainless steel "U" ring, with some flexibility in both high temperature and low temperature , It has good sealing with the butterfly; 3, the three-dimensional eccentricity of the butterfly valve, after rigorous calculations, "U" ring and the disc almost no friction, long service life, and with the more off the more tight Function; 4, the butterfly plate sealing surface by welding cobalt-based hard alloy, sealing surface wear resistance, long service life; 5, the unique structure of the butterfly valve, the "switch" can be completed by turning the valve stem 90 °. Operation flexibility, convenience, effort, not affected by the level of media pressure, sealing performance and reliable; 6, high temperature, low temperature, corrosion resistance. Electric butterfly valve actuator features: 1. Powerful features: intelligent, regulatory, switching. 2 small size: the volume is only equivalent to about 35% of similar products. 3. Easy to use: single-phase power supply, wiring is simple; using the original spherical bulge structure, making observation more convenient; free refuel point inspection, waterproof anti-rust, any angle installation. 4. Protection device has a double limit, overheat protection, overload protection. Full trip time 15 seconds, 30 seconds, 45 seconds, 60 seconds. And with manual function. 5. Intelligent CNC: The built-in module adopts the advanced computer monolithic and intelligent control software to directly receive the standard signal (4-20mADC / 1-5VDC) output by computer or industrial instrument to realize the intelligent control and precise positioning of the valve opening. Can also choose 3810 series or NA series of electronic angular travel agencies. Also can choose PSQ series or DYR series. ≥ DN300 diameter valve generally 380VAC electric actuator.
