Honeywell 40004802-010 Catridge for VC4043 Series Spring Return Valve

Description The VC4043 cartridge used in VC-Series valves determine the Cv (kv) rating and flow characteristic of a valve body. Replacing the cartridge rebuilds the valve to original factory specifications. 1000-series cartridges fit all 2-way VC bodies. 6000-series cartridges fit all 3-way VC bodies. For trouble-free operation of the product, good installation practice must include initial system flushing, chemical water treatment, and the use of a 50 micron (or finer) system side stream filter(s). Remove all filters before flushing. Do not use boiler additives, solder flux and wetted materials which are petroleum based or contain mineral oil, hydrocarbons, or ethylene glycol acetate. Compounds which can be used, with minimum 50% water dilution, are diethylene glycol, ethylene glycol, and propylene glycol (antifreeze solutions).       Features Use VCZZ1XXX with two-way valves. Use VCZZ6XXX with three-way valves. Quick and easy replacement of moving parts. Restores valve to factory-new conditions. Using different cartridge changes Cv and flow characteristic of body. Identical cartridge can have different Cv in bodies of different sizes.
