Electronic electric fine small three-way regulating valve is a special control valve for three-way regulation. It offers high control accuracy and stable, reliable operation.
The mixing (confluence) type is mainly used to combine two fluids into a third fluid, while the diverting (split) type is used to divide one fluid into two streams.
This product can replace two sets of single-seat or double-seat regulating valves used in combination. It is suitable for regulating and controlling liquids, gases, steam, and other media. Electronic electric actuators can be selected according to user configuration requirements.

Electric Sleeve Type Control Valve is an improved product of the conventional type. In addition to the advantages of ordinary sleeve valves, it offers good stability, strong versatility, and easy maintenance. It also features compact size, light weight, and large flow capacity.
Single-seat type is suitable for applications with strict leakage requirements and small pressure differences. Double-seat type is suitable for media with less strict leakage requirements and larger pressure differences.
A small-orifice throttling type can be used as a low-noise valve.

Step 1: Order and Design
Based on the operating conditions provided by the customer—such as nominal diameter, pressure, temperature, medium type, and control requirements—we determine the structural configuration of the electric control valve, the valve body material, the internal component configuration, and the selection of the electric actuator. We then generate production drawings and process documentation.

Step 2: Forging & Casting
In accordance with design requirements, major pressure-bearing components such as the valve body and bonnet are forged or cast. Materials typically include carbon steel, stainless steel, or alloy steel. After the blanks are formed, they undergo sand removal, grinding, and visual inspection to ensure that the basic components of the electric control valve are free of defects such as cracks and porosity.

Step 3: Machining
Precision machining is performed on components such as the valve body, seat, stem, and plug. This includes turning, boring, drilling, tapping, and sealing surface machining to ensure dimensional accuracy and fit tolerances, thereby guaranteeing the electric control valve’s sealing performance and control capabilities during subsequent assembly.

Step 4: Assembly
The machined valve body, internal components, seals, and electric actuator are assembled. During assembly, the stem concentricity is corrected, the valve plug stroke is adjusted, and the connection between the actuator and the valve is completed along with preliminary debugging, resulting in a fully assembled electric control valve.

Step 5: Testing & Quality Assurance
The electric control valve undergoes strength testing, seal testing, operational testing, and electric actuator functionality testing. Switching travel, feedback signals, and control accuracy are inspected to ensure the product meets relevant standards and customer requirements.

Step 6: Painting and Finishing
After passing testing, the valve’s exterior undergoes rust removal, painting, anti-corrosion treatment, and nameplate installation. Finally, cleaning, packaging, and final inspection are completed to ensure the product has a clean appearance and is suitable for transportation and on-site installation.

Featuring a compact size, light weight, simple wiring, high flow capacity, and high control accuracy, these devices are widely used in industrial process control systems across various industries, including power generation, petroleum, chemical, metallurgy, environmental protection, light industry, as well as in educational and research equipment.
