The Mesurflo® Pressure Independent Control Valves (PICV) from Hays Fluid Controls prevents the operating system from experiencing excessive flow. In conditions where higher than normal pressures occur, Mesurflo® Pressure Independent Control Valves (PICV) lowers total system flow. This saves energy and further reduces costs. Mesurflo® PICV also protects equipment from the detrimental effects of flow-induced erosion.

Mesurflo® Pressure Independent Control Valves (PICV) Delivers:

  • Durability: Designed with no tiny springs or thin rubber diaphragms that can weaken or rupture

  • Value: Warranted for life of the HVAC system with technology used by the U.S. Navy for over 40 years.

  • Stability: No oscillation or vibration as experienced with spring-type valves.

  • Clog Resistance: Changing orifice opening self-cleans passing debris.

  • Quiet: No metal internals.

  • Cost Efficiencies: Eliminates time-consuming system balancing and ensures proper flow at all terminal units.
