VCZA; VCZB Two-way Cartridge Cage Valves
Two-way Cartridge Cage Valves are intended for hydronic
applications in a normal indoor environment to control the flow of
hot water or chilled water glycol solution to 60% concentration.
These valves are designed for zone control of heating/cooling
systems, or to control individual fan coil, baseboard radiator or
convector applications. Depending on the model selected they can
be controlled by SPST or SPDT two position controller, tristate
(floating), or modulating proportional controller. For best control,
outdoor temperature compensation of supply water temperature is
recommended. 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.
• Quick open, linear, and equal percentage flow characteristics available
• Bi-directional installation
• 3000-series valves for floating and modulating non-fail safe applications
• 1000-series valves for two-position control
• High close-off rating independent of Cv
• Available with a variety of North American and international pipe fittings
• No tools required for actuator installation or removal
• Actuator removal does not require draining system
• Service is by replacement of cartridge, not valve body
• Cartridge replacement rebuilds valve to factory-new condition
