SD Series Quarter Turn Electric Valve Actuator Motorized Electric Actuator
Quarter Turn Valve Actuator Overview:
Quarter Turn Electric Actuators use electrical energy to open, close, or throttle valves that require highly accurate positioning. They are designed to automate the precise operation of valves that open and close through a rotary 90° motion (a quarter turn), such as ball valves, plug valves, choke valves, dump valves, and butterfly valves. Rotary quarter-turn actuators can also be used to automate dampers to regulate the flow of air in chimneys and air-handling equipment for the HVAC industry.
Quarter Turn Valve Actuators can be equipped with either an AC or DC voltage electric motor capable of delivering a wide range of torques for automated and responsive valve positioning without the complexity and cost of a pneumatic supply. Their compact design and relatively light weight are ideal for situations where installation space is limited, enabling additional clearance for alternative piping options.

Quarter Turn Electric Actuator Technical Performance:
1. Chinese and English debugging menu, simple and intuitive
2. Supports 3 control methods: (all are optical couple isolation)
A. Switch type control can choose jog control or save control.
B. Analog control standard 4-20mA, input signal impedance 100Ω, output signal impedance <750Ω. (standard configuration)
C. MODBUS bus control (optional)
3. It has phase sequence identification and correction functions. Three-phase power does not need to identify the phase sequence, and the device can operate normally when connected.
4. It has the power supply phase loss protection function. The three-phase power supply phase loss actuator automatically stops and displays the phase loss.
5. There are multiple protection measures:
A. Electronic limit limit
B. Over-torque protection
C. Signal interruption protection, stay in position, fully closed, fully open, three methods to choose from
D. Motor overheating protection
E. Stalled rotor protection, when there is a control command, after 8S, there is no feedback action and it is judged as stalled.
6. Equipped with 4-way alarm dry contacts, alarm items can be selected through settings
7. High-precision control, error ≤±1%, braking adopts delayed reaction braking, and current fluctuation is small.
8. With ESD emergency control function.
9. The highest protection level is IP67.
10. Implement standards IEC60259, JB/T8219-2016, GB4208-2017, GB3836.2-2010, GB3836.1-2010 and reference.
Our products are sold all over the world, you can rest assured.
