The type 1600CRT Apollo ProFlow PICV cartridge can replace existing cartridges in the valves. By choosing a cartridge with different parameters, the flow range of the valve can be adjusted without having to demount the complete valve. The cartridges can be exchanged with the system in-use (hot-swap)  

The type 1600, Apollo PICV is designed to eliminate existing heating and cooling system issues. Apollo ProFlow PICV’s are supplied in bypass configuration. Valves can be installed and flushed (forward and backward) at full bore prior to commissioning with the PICV mechanism safely out of the way. Once the system is clean and ready to commission, a simple rotation of the PICV head introduces the valve into the flow, and rotates the bypass out of the way.
