Valves

Building Automation Systems rely on various types of valves for on/off control in HVAC systems.  There are a range of styles for different types and sizes of pipes, including ball, globe, butterfly, pressure-independent, energy, zone and characterized control.  Valves play an important role in managing heating and cooling, zone control, system protection and energy efficiency.  E-Controls offers valves from manufacturers Siemens, Belimo and Johnson Controls.
