W-DP71-25Q (DN50-DN500)

Dynamic Flow Balancing Valve

  • The flow rate is factory preset, multiple ∆P ranges available for each size
  • Precision calibrated valve plug keeps the flow deviation no greater than ±5%
  • No on-site commissioning, saving labor costs
  • Dynamic Balance: When the system differential pressure generates fluctuation, the spool automatically adjusts the variable runner opening and can achieve the constant flow in the controlled area
