3 way chilled coolant valve
3 way chilled coolant valve description
For cooling, the 3 way chilled coolant valve uses a DC motor and a gearbox to control valve rotation.
The valve position is dependent on the DC motor; gearbox It is controlled by position sensors. The position sensor produces a corresponding voltage based on the angle of the valve.

3 way chilled coolant valves can be designed in diameters ranging from 16Øs to Ø25, requiring only changes to the pipe dimensions.
The Ø25 water valve allows for flow rate control from 5 L/MIN to 100 L/MIN.




The Problem vs. Solution
| Conventional Valve Issues | Our Premium Solution |
| Inaccurate control causes temperature swings (±2°C) | Equal percentage flow characteristic delivers stable, precise output (±0.5°C) |
| Leakage at closed port wastes energy (bypass flow) | Bubble-tight shut-off (≤0.1% leakage) prevents energy loss |
| Short lifespan in chilled water applications (condensation, corrosion) | Stainless steel stem + brass/bronze body resists corrosion, 100,000+ cycles |
How It Works: Technical Explanation
Operating Principle
A 3 way chilled coolant valve regulates chilled water flow by redirecting rather than stopping flow-maintaining constant system pressure while modulating temperature.
