Static Balancing Valve: Precise Flow Control for HVAC and Chilled Water Systems

A static balancing valve is a type of manual flow control valve used in HVAC, chilled water, and other hydronic systems to ensure proper water distribution across different zones. Once installed and calibrated, it helps maintain a steady flow rate in each pipeline branch, making it a critical component for achieving long-term hydronic balance.

Why Use a Static Balancing Valve?

In complex water circulation systems like central cooling or heating networks, uneven water distribution is a common issue. Some terminal units may receive too much flow, while others receive too little. This leads to:

Uneven room temperatures
Poor system efficiency
Increased energy consumption
“High flow, low ΔT” (temperature difference) problems

Installing a manual balancing valve at each branch helps allocate the correct amount of flow to every zone, ensuring uniform performance across the system.
