Characterized Control Valves (CCV and HTCCV) marks a true advancement in control valves combining high close-off capabilities of a ball valve with a specialized disc ensures an equal percentage flow characteristic.
Pressure Independent Valves
directly control the water flow required by the coil and are 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.
