Water Control Valves
In Chilled and hot water systems there is a need for automatic and manual control valves to control the flow of water in piping loops. Valves such as check valves, triple-duty valves, automatic flow control valves, automatic temperature control valves, and circuit setters can maintain the flow at a specified rate, reduce pressure, regulate temperature, dampen pulses in the hydronic loops, and protect the system from serious damage by preventing instability in a hydronic systems.

    Air handling unit ( AHU )
    An air handler, or air handling unit (often abbreviated to AHU), is a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to ductwork that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork.
