DDC Controls
Proportional Water Valve
The direct digital controller uses a time-based signal to drive the motor to its proper position. When
power is removed from the valve, it remains in its last controlled position.

The proportional water valve is used to provide accurate control of a hot
water heating coil to help maintain a zone temperature setpoint. The valve
is a ball design and comes in available in four different flow capacities for
proper controllability. The valves are field-adjustable for use as a two- or
three-way configuration. The valves ship in a two-way configuration with a
plug that is installed loose in the bypass port. Conversion to three-way
operation is accomplished by removing the plug from the "B" port. The valve
actuator contains a three-wire synchronous motor.
