RC series electric actuators are widely used in petroleum, chemical, power, smelting, energy, building materials, pharmaceuticals, paper making, water treatment, brewing, food processing, shipbuilding and building automation systems. Typical applications and in the butterfly valve, ball valve, air valve, plug valves and other rotary valve matching. 1, intelligent, proportional, switching everything; 2, the use of single-phase power supply, external wiring is particularly simple; 3, the volume is equivalent to about 35% of similar products; 4, special copper alloy forged worm gear, high strength, 5, the weight is only equivalent to about 30% of similar products; 6, free refueling, inspection-free, waterproof rust, any angle installation; 7, bearings and electrical components imported brand-name products; Overheat protection, overload protection; 9, aluminum die-casting appearance, fine and smooth; 10, the use of heat-resistant flame retardant wire, heat aging, safe and reliable; 11,1500 V voltage, special wire lock cable lock; Set, display valve position, mathematical setting, high clarity. 13, Optional torque: 50 NM, 100N.M, 250 NM, 500 NM, 600N.M, 1000 NM, 2000 NM (Please choose when ordering) 14, With ball valve: DN15-300, Butterfly: DN50-600 ( Please choose when ordering) 15, Power: 220V AC 50 / 60HZ, Special can consult the relevant departments 16, Ambient temperature: -30 degrees -60 degrees 17, Manual operation: Hand crank with random 18, Electrical, mechanical double limit 19, waterproof rating: quite IP67 20, the installation direction: can be installed at any angle in all directions 21, the position measurement: optional switch, potentiometer or 4-20mA 22, the box material: die-casting aluminum alloy 23, into the line interface: PF1 / 2 "into the line lock 24, corner 0-90 degrees; Special to consult the relevant departments 25, 30/60/120 seconds trip optional 26, overheating protection 27, can be switched by external power or external input signal to achieve open, Off and the middle position of the control 28, can directly receive the power switch or computer, instrument output 4-20mA DC / 1 --- 5V DC and other signals to achieve intelligent control of the motor valve and precise positioning Intelligent Add-on Description: 1, Control accuracy: 0.1% -3.0% ( Adjustable); 2, can set the actuator positive and negative action modal and input signal interrupt "interrupt" mode-OPEN, STOP, SHUT; 3, can be set whether to allow electronic system 4, output actuator position signal: low drift output 4-20mADC corresponding actuator fully closed to fully open, the signal is completely isolated from the input (optical isolation); 5, over-temperature protection; 6, The input signal corresponding to the actuator action range (generally calibrated for the electric actuator fully closed, fully open position); 7, manual / automatic interference-free switching; 8, the actuator stall detection control; 9, can be set to allow changes Precision or re-tune the time; 10, the password lock to prevent misuse; 11, special requirements can be customized.
