Overview
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 50% 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 either a low or line voltage SPST or SPDT two position controller, or tristate (floating) or modulating proportional controller. 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.

Features

• Quick open, linear, and equal percentage control characteristics available. • Bi-directional installation. • Models for two position or proportional 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.
