3-Way Ball Valve and Actuator.
Description
Designed to provide excellent equal percentage ow 
control, Three-way Ball Valves are available in 1/2 to 
2-inch line sizes and are 1/4-turn rotary control valves. 
These ball valves are designed to couple with an 
OpenAir actuator.
Features
• Universal mounting plate accommodates different 
actuator sizes
• Variety of ball sizes and ow coefcients minimizes 
the need for downsizing pipes and accurately controls 
uid through coils
• Industry leading close-off
• Actuator and plate can be rotated to facilitate 
installation and wiring
• Standoffs and mounting plate provide a thermal barrier 
between the actuator and valve
• Plastic mounting plate, extensions, and handle do not 
condensate in chilled or hot water applications
• Operating handle can manually operate valve in the 
event of a power failure
• Available as on/off (2P), oating (3P), or proportional 
control
• Spring return or non-spring return
Applications
Ball Valves can control hot or chilled water and up to 
50% glycol solution in convectors, fan coil units, unit 
conditioners, radiation, and reheat coils.
Application Drawings
The parabolic shape of the ow optimizer orice allows a 
slow opening valve. Equal movements of the valve stem 
at any point of the ow range changes the existing ow an 
equal percentage regardless of the existing ow. The ball 
valve equal percentage ow characteristic mirrors the ow 
characteristic of a coil, resulting in linear heat transfer.
Ball Valve Equal Percentage Flow Control.
