CENTORK electric actuator designed with unique concept has been widely used in various industrial production processes, such as harsh and changeable environmental conditions, long-term static state, corrosive environment, low maintenance state, remote control and so on.
Motor: specially designed for valve drive, low inertia and high torque can ensure accurate and reliable drive/service. S2- 15-minute short-time working system is adopted for the on/off type, and S4 working system is adopted for the adjustment type.
Manual operation: CENTORK electric actuator has emergency manual operation function, and electric drive is preferred, and the handwheel does not move when the actuator is running.
TCS: planetary gear transmission device with patented torque/thrust control system, which features: high mechanical efficiency: > 95%; Especially when telling the operation, the accuracy of controlling torque/thrust is high; Low working noise; Small capacity
Protection: CENTORK electric actuator adopts high protection level (protection level of EN60529 IP67), which can ensure normal operation in extremely harsh environment. All external bolts are made of stainless steel, and can also provide IP68 protection level required by users.
Switch signal system: CENTORK electric actuator has two independent control mechanisms: torque/thrust switch based on PTCS system; The limit switch has two independent high-precision repeat counters. Both mechanisms are easy to set up in the field.
Various options for users to select and adjust also include: alarm lamp, mechanical position indicator, impedance position signal, 2, 3 or 4 wire 0 or 4-20MA/0- 10V position signal, adjustable intermediate position signal and anti-condensation heater.
Electrical connection: According to the different needs of users, three different schemes are adopted to control the electrical signal connection of the motor power box: slot connector (bolt connection), terminal connector (line end press-fit connection) and slot connector (wire harness connection).
★ Modular design: it can meet all kinds of requirements (digital and non-digital): 1, multiplex electric actuator, torque: 15 ~ 4000 Nm, rotation speed: 2.75 ~ 224rpm. 2. partial rotary electric actuator, torque: 280 ~ 350000Nm, 90 switching time: 6 ~ 900 seconds. 3. linear electric actuator, thrust: 7 ~ 200KN, stroke: 25 ~ 500 mm
★ Working mode, 1, S2- 15-minute periodic working mode. 2.S4-25% modulation working system
★ The transmission device adopts PTCS system (planetary torque control system) and new patented system, which greatly improves the execution efficiency, reduces the noise and controls the torque with high accuracy.
★ The protection level and standard model protection level are IP67. According to EU 60529 standard, IP68 can be selected according to working conditions. The test condition is to complete 10 switching actions within 72 hours at a water depth of 6m.
★ Flexible programming ensures adaptability to different working conditions, self-diagnosis function, convenient maintenance and quick problem solving (emergency manual function is also available, and motor work is preferred).
