Resideo vczz1100/u Vc Series Replacement Cartridge

Product Description

The RESIDEO vczz1100/u is a replacement cartridge designed for use with VC Series valves. This cartridge serves as the internal flow-control element within the valve assembly, regulating fluid passage in hydronic heating and cooling systems. Licensed plumbers and HVAC technicians install this component when a VC Series valve cartridge fails or degrades, restoring proper valve function without requiring full valve body replacement. Most kit configurations include a cartridge wrench to facilitate removal and installation of the cartridge in the field.

This cartridge is suited for residential and light commercial hydronic systems where VC Series valves are already installed. It is a direct replacement component, allowing technicians to service an existing valve assembly in place rather than replacing the entire valve. This reduces material cost and labor time on service calls. It is particularly useful in balancing valve and zone valve applications common to hot-water heating systems.
