Supply of electric soft seal butterfly valve Shanghai plug high D971X electric soft seal butterfly detail parameters ..

About Shanghai bolt D971X electric butterfly valve with integrated high-power structure, access to 220VAC power to control operation can also be added to the control module, the input control signal (4-20mADC or 1-5VDC) adjustment control. It has a strong functions, small, light and pleasant, reliable, simple matching dollars, flow capacity of normal, clean media, the choice of the valve plate plus soft seal (rubber ring, PTFE ring) to reduce leakage (up to 0.01 %), high temperature and pressure conditions can choose three eccentric hard seal body. Can be specified when ordering. It can be widely used in food, environmental protection, light industry, petroleum, chemical industry, teaching equipment, paper, power industry until the industrial process control systems. D971X electric butterfly valve standard design standards: GB / T2238-1989 flange size: GB / T9113.1-2000; GB / T9115.1-2000; JB78 length of the structure: GB / T12221-1989 pressure test: GB / T13927- 1992; JB / T9092-1999 D971X electric valve actuators: electric actuator features: 1. strong function: intelligent, regulated, switched mode. 2. Compact: volume equivalent to only about 35% of similar products. 3. Easy to use: single-phase power, simple wiring; use the original spherical convex structure, make it easier to observe; oilless free check, waterproof rust installed at any angle. The protection device has double limit, thermal protection, overload protection. Full travel time 5 seconds, 10 seconds, 15 seconds, 30 seconds, 45 seconds, 60 seconds. And with manual functions. 5. Intelligent NC: standard signal output from the built-in computer chip and module using advanced intelligent control software directly to the receiving computer or industrial instruments, etc. (4-20mA DC / 1-5VDC) intelligent control and precise positioning of the valve opening. Large diameter valves generally use 380VAC electric actuators.
