DELTA P VALVES
Precision Flow for HVAC Performance
A pressure-independent control valve that maintains required flow as system pressure changes, helping improve hydronic balance, comfort and HVAC efficiency.

Precise Coil Flow Under Changing Building Loads
The DeltaPValve combines modulating flow control with an internal differential-pressure regulator. As valves open and close throughout a variable-flow HVAC network, the available pressure at each coil continually changes. The valve automatically compensates for these fluctuations so that flow follows the building-control signal rather than pressure variations elsewhere in the system. This supports stable coil operation across chilled-water, heating-water and selected glycol applications.
THE SYSTEM CHALLENGE
Variable-Flow Systems Rarely Operate Under Design Conditions
Large HVAC systems are designed for peak demand but spend much of their operating life at partial load. As zones call for more or less heating or cooling, changes in network pressure can cause conventional valves to deliver too much or too little water. This may result in coil overflow, unstable temperatures, excessive pumping and weakened chilled-water delta T.
Deliver the Right Flow at the Right Load
The valve’s internal regulator compensates for changes in differential pressure, giving the modulating control element more consistent operating conditions. Flow can then track actual heating or cooling demand more accurately, helping reduce overflow, maintain coil temperature differential and support stable indoor comfort.
