SD Series Quarter Turn Electric Valve Actuator Motorized Electric Actuator

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 Valve Actuator Specification:

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.

Wuxi Weishi Industrial Complete Equipment Co., Ltd. was established in May 2015. The company is mainly engaged in environmental protection EPC general contracting (bulk material transportation/flue gas treatment/water treatment) and heavy industrial equipment trading have formed the "two wings - one body" strategy and management model of Wuxi Weishi and Vietnam Xinke. The company currently has more than 150 employees, including 5 with senior professional titles or above, 10 with master's degrees, and 58.6% of employees have bachelor's degrees or above.

After years of intensive cultivation and accumulation in the field of steel metallurgy and cement EPC general contracting, the company's customers include Hoa Phat Group, Vietnam Steel Corporation, Chuncheng Cement Factory, Yuanhe Cement Factory and other well-known Vietnamese enterprises. The company has successfully completed a number of large-scale EPC general contracting projects such as steel rolling water treatment, flue gas desulfurization and dust removal, and comprehensive material transportation, and has maintained stable growth in turnover year after year, with annual turnover reaching 300 million yuan. Relying on the advantages of Vietnam's rapid economic development and huge market demand, the company is actively exploring international markets such as Southeast Asia and has broad development prospects.
