triple eccentric butterfly valve mainly has several kinds of models D943 electric triple eccentric butterfly valve, D363H welded two-way pressure triple eccentric butterfly valve, triple eccentric butterfly valve USES three eccentric structure design, the valve plate in the range of travel are opened and closed with the seat without friction, eliminates the rotation type of control valve for the seat open, close and seat wear and tear caused by leakage. Seat adopts multilevel structure, using the combination of metal and nonmetal materials constitute a sealing surface. Performs well in high temperature and low temperature conditions. This series of butterfly valve long service life; Sealing performance is outstanding, is suitable for almost all of the gas in the industrial process control and the regulation of liquid and cut off the use. D943 electric triple eccentric butterfly valve belong to long using time, energy-saving electric butterfly valve. Its structure using the 3 d design of principle of heart valve seat adopt hard and soft sealing compatible multi-level structure, treatment is excellent. Electric triple eccentric butterfly valve consists of body, disc, multi-level seat, valve stem, drive mechanism and so on the main parts. Electric metal sealing butterfly valve with angular travel electric actuators can be directly receiving computer or industrial instruments such as the output of 4 ~ 20 madc or 1 ~ 5 VDC control signal, according to the valve position feedback signal is compared with the set value deviation interval adjustment to smart actuator drive motor ( The PID) To achieve with actuator of the opening of the valve or other device of accurate positioning, and at the same time the output of 4 ~ 20 madc position feedback signal. So electric metal sealing butterfly valve is mainly applied to metallurgy, electric power, petroleum, chemical, air, gas, combustible gas and water supply and drainage automation control. D943 electric triple eccentric butterfly valve is used in 3 d design of principle of eccentric make sealing surface space trajectory to achieve ideal, no friction, no interference with each other, together with sealing material is properly selected, so that the butterfly valve sealing, corrosion resistance, high temperature resistance and abrasive resistance and so on. Its main characteristics are as follows: 1, the small open torque, flexible, convenient and saving energy. 2, 3 d braided structure, make the butterfly plate the closed tight, the sealing performance is good, without leakage. 3, high pressure resistance, corrosion resistance, wear resistance, long using time, etc. D363H welded two-way pressure D363H triple eccentric butterfly valve welding type two-way triple eccentric butterfly valve USES the same as the valve body material processed into sealing ring, use electric or pneumatic drive. Its applicable temperature with the valve body material, generally applicable to the industry, metallurgy, environmental protection and ventilation to adjust medium flow in pipe, make the disc plate freely within the range of 90 ° rotation to achieve the goal of open/close or adjusting medium flow. Its main features are: 1, novel design, reasonable, unique structure, light weight, rapid opening and closing. 2, small operation torque, easy to operate, saving smart. 3, using adaptive materials to meet the medium low, medium and high temperature and corrosive medium, etc. D363H welded two-way pressure main technical parameters of triple eccentric butterfly valve type: D363H pressure: PN25 caliber: 25 Operation: 800 turbine operating body: A216 - WCB disc: A216 - WCB sealing ring: SS304 + graphite stem: AISI 410 structure length: L = 470 mm connection mode: welded triple eccentric butterfly valve American standard spun is cone Angle is an Angle to the inclined Angle, so that the valve stem and valve body center eccentric decreases, and also open torque is less. Widely used in metallurgy, electric power, petroleum chemical industry, water supply and drainage, and municipal construction and other industrial pipelines, used to adjust flow cutoff and body. Main technical parameters of triple eccentric butterfly valve pressure: American standard 300 lb caliber: 25 800 models: D673W operation: single acting pneumatic actuator body: A351 CF8M disc: A351 CF8M seal: SS316 + graphite stem: F316 structure length: 61 mm design standard: API 609
