3-Way Valve
The ESBE VRG series of 3 & 4-way valves are designed
to mix water to the appropriate temperature to
meet the zone or system requirements within
heating and cooling systems.
The redesigned VRG valve replaces the MG and
G series of rotary valves providing additional
operational features. By either mixing or diverting,
the uid temperature leaving the valve is
regulated by the VRG in either a manual operation
or automatically when coupled with the ARA600
Series or 90 Series electronic motor actuator. These
actuators are typically connected to an outdoor
reset controller, DDC system or boilers with
integrated controls.

Each port of the VRG valve is stamped with an identiable shape. These distinct stamped shapes provide
a reference during the installation and trouble shooting of the valve.

Valve Position:
Typical Installation:
Located on the stem of the VRG is a position indicator in the shape of an arrow. This arrow correlates to the orientation of the internals of the
valve. Depending on the required 90° travel of
the valve from port to port, the setting indicator
can be installed to reect the direction of travel.
