Ball Valves VBB/VBS Series

Ball Valves


The Schneider Electric VBB/VBS Ball Valves Series are interchangeable valves and valve actuators, making it simple to implement upgrades and accommodate building system changes. As assemblies, the SmartX Valve Actuators and VBB/VBS Ball Valves Series gives users the freedom and flexibility to easily optimize and precisely control a wide variety of applications. They also accept floating and proportional control signals from a DDC system, controller, or thermostat for control of hot or chilled water, and solutions of up to 60% glycol. This makes them ideal for installation in VAV re-heat, fan-coil, and unit ventilation applications. The VBB/VBS Series proportional actuators allow easy configuration of control signals via Dip Switch. Dip Switches are accessed conveniently through an easy to open access hatch on the side of the actuator, eliminating the need to remove the cover of the actuator. Kele is the leading supplier of building automation products. When you need the right product, right now, count on Kele.
