1. Working Principle of Electric 3-Piece Ball Valve
✅The valve body adopts a three‑piece split structure. The electric actuator drives the valve stem to rotate the ball through a 90° angular travel. In the fully open position, the ball bore aligns with the pipeline for full flow; in the closed position, it blocks the medium passage. Referring to fluid resistance calculations in the Journal of Fluid Mechanics, the pressure drop of the three‑piece full‑bore structure is far lower than that of one‑piece valves.
✅Equipped with a stainless steel three piece high platform electric ball valve high‑platform ISO5211 standard mounting base, the actuator requires no adapter bracket. Disassembly and maintenance can be performed without removing the entire pipeline section—simply loosen the body bolts to replace the seat seals, significantly reducing maintenance costs.
2. Core Parameters for Electric Actuator Selection
When purchasing an actuator for a three piece full port electric ball valve, four core parameters must be confirmed:
-
Supply voltage (DC24V / AC220V / custom special voltages),
-
Control signal (on‑off type / 4‑20mA modulating type),
-
Protection class (IP rating),
-
Torque load.
✅For high‑viscosity or high‑pressure media lines, a higher‑torque model is required; for explosion‑proof conditions, choose an explosion‑proof electric actuator; for low‑temperature corrosive media, match with a 3pc stainless steel ball valve custom body material.
✅Standard actuator parameters on the market are largely homogenised; only professional manufacturers can accommodate non‑standard voltage and special feedback signal requirements.
3. Main Application Scenarios
This valve series is widely used in water treatment, food & pharmaceutical, chemical & oil & gas, and HVAC automation pipeline systems.
-
In the food industry, sanitary three‑piece ball valves are selected;
-
For chemical corrosive pipelines, 316L material is customised;
-
For high‑pressure oil & gas scenarios, a pneumatic three piece welded ball valve with welded‑end construction is matched to meet high‑pressure sealing requirements, suitable for various automated remote‑controlled pipeline systems.

4. Customisation and Delivery Advantages of Professional Manufacturers
☑️Most manufacturers on the market can only produce standard models of three‑piece electric ball valves. When faced with special connections, special media, non‑standard voltages, or extreme temperature/pressure conditions, they suffer long delivery times and immature solutions.
☑️As an original manufacturer, CHCV has complete forging, assembly, and testing production lines, enabling rapid customised solutions.
In May 2023, we collaborated with Inoxidables, a local enterprise in Guadalajara, Mexico. Their chemical pipeline project required custom acid‑and‑alkali‑resistant 316L three‑piece electric ball valves, special American NPT extended threaded connections, and 110V North American custom actuators. Regular traders could not deliver quickly. Our company completed drawings, samples, and full factory hydrostatic and pneumatic tests within 7 working days, successfully delivering the batch order. The overseas project has been running stably for 3 years without any leakage issues.
📌Leveraging our in‑house processing technologies and custom production lines—whether for welded, clamped, extended‑flange special connections, or for corrosive, low‑temperature, flammable, or explosive special media—we can rapidly respond to non‑standard requirements, accommodating both large‑scale standard orders and small‑batch custom projects.
