APPLICATION
The VP5 13A (normally open) and VP5 13B (normally
closed) water valves provide proportional control of unit
air conditioners using hot and/or cold water as the con-
trolled medium.
OPERATION (See Fig. 1)
An increase in control air pressure from the system
temprature controller proportionally drives the VP5 13A
closed or the VP513B open, modulating the medium’s
flow through the coil.
