Festures of Flow Balancing Valve

  • Good sealing, no penetration, easy to adjust the rotation;
  • Small mounting space, accurate and clear opening indication;
  • The use of inclined valve core and stem is more fluid flow in the valve
  • The surface is smooth and clean, and the appearance is delicate and beautiful.
  • Once-through Structure, Small Fluid Resistance
  • Numeral Handwheel, Accurately Debug Balance
  • Easy Connecting with Intelligent Instrument
  • Self-balancing Design
  • Hold Complete Cut Off Function

Flow Balancing Valve Working Principle


The valve regulates the flow rate of medium through its valve body, balancing the valve stem up and down by turning the regulating valve handle, adjusting the flow path and changing the flow curve characteristics. Pressure gauges equipped on the balance valve body are used to measure pressure differential, which can be used to detect and adjust the flow rate.

Flow Balancing Valve Installation and Commissioning

This valve can be installed either on the water supply pipe or on the water return pipe. Generally, it is recommended to be installed on the water return pipe, especially on the high-temperature loop. For specific use, please consult ZECO Valve Group.
