product series features

Compensates for pressure variations to maintain system performance at varying loads
Predictable flow throughout valve travel provides favorable energy savings
Helps to maintain desired delta T and reduces additional chiller staging
Constant flow performance reduces actuator movement and hunting to extend actuator life
Valve is sized based on coil flow rate (GPM) which simplifies valve selection and saves time without calculations
Small (compact) size for tight spaces

Series Description

The Belimo PIQCV Series valves combine a differential pressure regulator with a 2-way characterized control valve to supply a specific flow rate regardless of system pressure fluctuations. The PIQCV Series offers all the advantages of the PICCV series but in an ultra compact configuration. The valve performs the function of a balancing valve and a control valve in one unit. PIQCV valves can be used to regulate flow through air handling unit heating and cooling coils, fan coil units, unit ventilators and VAV reheat coils.
