Chilled Water Valve
(3 Way) The chilled water valve has an indication of flow on the stem. The actuator is securely
attached to the top of the valve so that when there is a demand for cooling the valve
opens allowing water to flow through the coil. No demand, the water goes through the
bypass (0 VDC no demand, 10 VDC 100% demand).
