Design Features:Balancing Valves are designed specifically for heating/air conditioning systems in multi-story commercial buildings. Balancing Valves provide a means of adjusting and reading the flow in condenser and hot or chilled water systems. These valves help maintain the desired flow, balance point and temperature throughout the building. Balancing valves are available in 1–24” (25–600mm) sizes of the proven PEC Eccentric Plug Valve design with two options for upstream and downstream flow taps.
