1 Ballorex Dynamic Description The Ballorex Dynamic valve is a combined pressure independent flow limiter and control valve which maintains a constant flow independently of pressure changes in heating or cooling systems. Installed with an actuator the Ballorex Dynamic combines an automatic flow limiter and a two-way control valve. Having full control authority the valve reacts instantly and adjusts the flow according to the Building Management System (BMS) or room thermostat signal. Without actuator the Ballorex Dynamic works as an automatic flow limiter. In this way the valve ensures the design flow in terminal units. The Ballorex Dynamic valve also prevents overflows in the systems at any time Versions Dimensions Flow Benefits DN15, DN20, DN25 DN32, DN40, DN50 L (Low), S (Standard), H (High) 00010_ _ENG 1 Automatic balancing Direct flow measuring of actual flow by the use of built-in Venturi nozzle Easy system error detection by actual flow verification Always 100% valve authority for perfect flow control as full stroke is independent of presetting Installation in any position and directly onto bends, reducers and flexible pipes No overflows and no unnecessary energy consumption Better thermal comfort High flow control accuracy with only ±7% tolerance Commissioning not needed Easy valve selection Colour coded cartridges for easy identification Easy system flushing due to removable cartridge Low installation cost due to the two in one motorized valve and automatic flow limiter construction Precise pump tuning for improved energy saving when verifying flow via measuring points
