10 Magnetic mixing valve
Mixing valves which are optimally matched to the units are
available for easy installation of RoofVent
®
units. They have
the following specifications:
■ modulating control valve with magnetic drive
■ with integrated position control and response
■ separate manual control for emergency operation
(connection to AC 24 V = valve OPEN)
■ ready for connection to the connection box
