Shanghai Rong Titanium Valve Manufacturing Co., Ltd. is {D971X Electric Butterfly Valve} professional manufacturers. The quality of survival, integrity and development, has a collection of scientific research, design, manufacture, sales and service in one of the high-quality workforce, strong technical force, advanced production technology. Sophisticated processing equipment, sound detection equipment, a sound quality assurance system to ensure product quality and reliability. Electric Butterfly Valve Product Description D971X Electric Butterfly Valve double eccentric structure, with more and more tightly sealed off function, a reliable sealing performance. Sealing material selection matching stainless steel and nitrile rubber with long service life. Rubber seals can be located on the body, it can be located in butterfly board, applicable to the different characteristics of the medium, for users to choose. Disc with frame structure, high strength, flow area, flow resistance. Overall paint, can effectively prevent corrosion and replace the seal as long as the seat material, can be used in different media. D971X electric butterfly valve on the folder with two-way sealing function, the impact of the installation from the media flow control, are not subject to spatial location can be installed in any direction. This valve unique structure, flexible operation, effort, and convenient. Structural characteristics and uses D971X electric Wafer butterfly valve Wafer center plate structure, mainly made up of body, valve plate, valve shaft, valve seats and transmission components, simple and compact structure, small, lightweight, easy to transport, installation, dismantling; 90 hoist °, the switch quickly, a small operating torque, energy light; good sealing performance, long life, can achieve zero leakage; its flow characteristics similar to the straight line, regulated performance. D971X electric butterfly valve for rubber seal on the folder, when you close the disc and seat good sealing performance, bi-directional sealing performance, small torque value, the valve remains 100% zero leakage at operating pressure between the disc and seat and seal friction is small. Valve by the valve shaft driving the valve plate, the valve plate is rotated 90 ° to do. Hoist flexible disc, no jam, beat phenomenon, small torque. Purpose: The Hatch High Valve Manufacturing Co. developed midline Wafer soft seal butterfly valve, double eccentric butterfly compact flange, 90 ° rotary switch easy, reliable sealing and long service life. Is widely used in water plants, power plants, steel mills, paper, chemical, textile, food, etc. to the drainage, gas pipes for regulating traffic and closure of media role. Actuator Electric Actuator Technical parameters: Power AC110,220,380V, DC24, nominal diameter DN50 ~ 1200mm, the output torque 50N · M ~ 2000N · M, nominal PN0.6,1.0,1.6Mpa, function selection: Switch type, passive contact type, valve position feedback signal, intelligent regulated. Suitable temperature ≤120 ℃, suitable medium water, gas, oil and weak corrosive fluid, the input signal 4-20mA, 1-5V, 0-10V; output signal: 4-20mA, 1-5V, 0-10V. Easy to use: single-phase power supply, simple wiring; using original ball protruding structure, making it easier to observe; avoid refueling point inspection-free, waterproof rust installed at any angle. Protection device has a double limit, thermal protection, overload protection. Full travel time of 5 seconds, 10 seconds, 15 seconds, 30 seconds, 45 seconds, 60 seconds. And with manual functions. Standard signal using advanced computer chip built-in modules and intelligent control software directly receiving computer or industrial instrumentation output (4-20mA DC / 1-5VDC) intelligent control and precise positioning of the valve opening. 3810 series can also be used or PSQ series, large diameter valves generally use 380VAC electric actuators.
