How to Design a Gear Motor for Electric Ball Valve Actuator

Jiaming CaiApril 25, 2023

What is Electric Ball Valve Actuator?

An electric ball valve actuator is a mechanical device used to control an electric ball valve, which usually consists of a gear motor, a signal device (encoder) and a control circuit board. It can control the switch state of the electric ball valve according to the signal of the encoder, so that the water flow can reach the predetermined water pressure and flow rate, and achieve the control function of the fluid pipeline.

Runxin Electric Ball Valve

Electric ball valves are widely used in the fields of agricultural irrigation, water treatment, and industrial water supply because of their durability, small flow resistance, corrosion resistance, good wear resistance, and long service life.

With the development of automated agriculture, the market for electronic ball valves is increasing. DONCEN MOTOR cooperated with Wenzhou Runxin Manufacturing Machine Co, the largest electronic ball valve manufacturer in China. DONCEN provides customized gear motor solutions for RUNXIN ball valves to improve the market competitiveness of RUNXIN electric ball valves.

Design requirements for electric ball valve actuator motor

DONCEN Motor has developed the following design requirements according to the operating environment and working conditions of the electric ball valve actuator.

  • IP67 Waterproof:The DONCEN Motor custom waterproof cover covers the tail of the DC motor. Customized seeling rings will increase the overall waterproof function of the motor. At the same time, the customized upper end cap can ensure the waterproof performance of the top. The waterproof rating of our PG42 series can be IP67. It ensures that the motor can work safely on the ball valve actuator.
  • Long Working Life: Doncen choose long-life brushed motors or brushless motors. Ensure that the electronic ball valve can work for a long time.
  • Customized Shape:The internal space of the ball valve is limited.DONCEN will design the shape of the gear motor according to the requirements of customers. We provide Geared motors in different shapes such as square gearboxes and planetary gearboxes.
  • Encoder avaliabe:Custom motor rear axles can be fitted with magnetic encoders
  • Corrosion resistant material:The overall casing material of the motor is all customized, and corrosion-resistant materials are used.
