Belimo Pressure Independent Characterized Control Valve (PICCV) Assembly

Pressure independent valves directly control the water flow required by the coil and is not affected by pressure fluctuations in the system. The valves are selected based on the GPM requirements of the coil and no Cv calculations are needed. By precisely controlling the flow, the Pressure Independent valves eliminate the need for balancing valves, thus reducing the installation and balancing cost. By far, the biggest benefit for the owner comes in the form of energy savings by eliminating overflow thru the coil. Overflow wastes energy by over pumping and is the main cause of the low Delta T syndrome in chilled water systems.

The Pressure Independent Characterized Control Valve (PICCV) combines a differential pressure regulator with a 2-way control valve to supply a specific flow for each degree of ball opening–regardless of system pressure fluctuations. The valve performs the function of a balancing valve and control valve in one unit. Therefore, the flow characteristic and operation of the valve is not distorted in the system.

The Pressure Independent Characterized Control Valve is typically used in air handling units on heating and cooling coils, and fan coil unit heating or cooling coils. Some other common applications include unit ventilators and VAV reheat coils. This valve is suitable for use in a hydronic system with constant or variable flow.

This valve is designed with MFT functionality which facilitates the use of various control input.
