  Product Description       DKJ-B  quarter-turn explosive-proof electric actuator         is the terminal control device of industrial process measurement and control system. It can transform the system control signal to angular displacement of the output part so as to control the position of closure software in the valve or other regulating mechanism, thus the controlled medium can work as indicated by the system.     DKJ-B series quarter-turn explosive-proof electric actuator is designed according to national standard GB3836.1-2000 and GB3836.2-2000 “explosive gas environment used electric equipment” and is inspected qualified by national standard explosive-proof institution. The explosive-proof type of this product is flame proof; explosive-proof grade is dIIBT3. It can work in II type places containing gas whose propagation degree of explosion is lower than grade B, T3 group gas.   DKJ-B series quarter-turn explosive-proof electric actuator can be divided into proportional type and integral type according to control mode.          Main technical performance:        1. Input signals: mode II: 0~10 mA, DC; mode III: 4~20 mA, DC 2. Input passages: 3 3. Input channel resistance: mode III: 250Ω, mode II: 200Ω 4. Output thrust: see dynamic parameter 5. Whole travel time: see dynamic parameter 6. Basic error: ±2.5% 7. Explosion-proof grade: dⅡBT3 8. Damping characteristic: ≤ a half and three cycles 9. Return difference: 1.5% 10. Voltage of the power supply: 220V(+10%,~15%)  frequency: 50HZ 11. Temperature of the operating environment:    Actuator: -10~+55°C or -25~+70°C 12.It is permitted that explosive gas, whose propagation degree of explosion is lower than grade B, T3 can exist in the air, but corrosive gas is prohibited.      Specifications and types                    Dimension Figure:         Wiring diagram          Base features:    •Light weight and small size, •Easy to adjust the end position of stoke control and set torque switch •High accuracy of driving medium, •Mechanical adjustable stop for valve and position control. •Good manual/electric declutch design •Possessing ideal outdoor performance •Various flange connection modes •Local/remote-control shifting function   Our valves are widely used for petroleum processing, chemicals, food, medicine, textile, paper making, hydro electricity engineering, shipbuilding, wafer supply, metal disease and energy engineering.   Product Show       Our Services       Company Information
