Working Principle of Electric Ball Valve:
Core Component for Automatic Fluid Control, Choose Reliable Solutions from Yuanlun Valve
With the intelligent development of HVAC central air conditioning, building automation and industrial pipelines, electric ball valves serve as critical actuators in automatic fluid control systems, widely adopted in water circulation, water supply & drainage, heat exchange units and other projects. This article elaborates on the structure and working principle of electric ball valves, and provides product selection guidance from Zhejiang Yuanlun Valve, the original manufacturer.
1. Structure and Working Principle of Electric Ball Valve
A complete electric ball valve consists of two main assemblies: electric actuator and ball valve body. The actuator generates torque upon receiving electrical signals, driving the valve stem to rotate the ball plug by 90 degrees. When the through bore of the ball plug aligns with the pipeline, the medium flows through; rotating the ball by 90° blocks the passage to cut off medium flow. The products fall into two categories:
On-off Electric Ball Valve: Provides fully open / fully closed switching control.
Modulating Electric Ball Valve: Receives analog signals to adjust opening at any position for precise flow regulation.
2. Application Scenarios
Electric ball valves are commonly used in central air conditioning HVAC systems, zoning control for floor heating, building water supply, sewage treatment, light industrial fluid transportation and other applications. They are widely applied automatic control valves for intelligent buildings and automation retrofits.
