Zone Valve Parts

Replacement and repair parts for hydronic zone valves and fan coil valves. The range includes Honeywell Home VC series replacement cartridges for 2-way valves, rebuild kits for VU52 and VU53 fan coil valves, ball and O-ring kits, thermostatic radiator valve cartridges and adaptor kits, plus complete MrPEX zone valves and Viega parts.

Identify the existing valve series and model before ordering, since cartridges and rebuild kits are specific to each family. Check whether the valve is normally open or normally closed, its flow characteristic and Cv, and whether you only need the cartridge or a new actuator head as well.
