1. Application
The VC series 2-position hydronic valves are used in
domestic and small commercial applications to control
the flow of hot and/or cold water or glycol solution to
50% concentration. They consist of an actuator, valve
and a replaceable cartrige assembly.
These 3-Way valves are designed for ON-OFF control
and can be piped for either diverting or mixing valve
applications for domestic hot water service, in central
heating and/or cooling systems; or for individual room
temperature control (fan coil, radiator or convector
applications).
Depending on the model selected, they can be cont-
rolled by either a low or line voltage SPST
or
SPDT
controller, such as a room thermostat,
a chronotherm or other suitable two-position controller.
