DRxxGMLA / DRxxxGFLA
APPLICATION
The DRxxGMLA / DRxxxGFLA rotary valves provide water
temperature control in heating and air conditioning
applications.
These valves are designed for accurate mixing control of
supply water temperature in heating and air conditioning
systems.
Its sturdy construction ensures a long and reliable operating
life when used in combination with M6061/VMM and
M7061/VRM actuators.
3-WAY ROTARY VALVES PN 6

OPERATION
The valve controls a mixing water temperature with a rotating
plug. The plug adjusts with two control curves the water flow
of two inputs. The required flow water temperature is reached
by adding a proportion of return water to the boiler hot water.
For optimum control performance, the DR has special control
characteristics.
