Overview

• Motor-driven 3-port diverter valve
• no flow reduction
• Actuator can be replaced without disassem-
bling the valve
• Easy manual operation
Application area:
The motor-driven 3-port valve VA32 is used in solar
and heating systems, in which smaller parts of the sys-
tems can be controlled separately or single equipment
can be switched on or off.
The valve is equipped with an emergency manual con-
trol, an integrated relay which can be controlled via
an on-off control signal or directly via a potential-free
changeover contact.
characteristics:
Compact size and modern design, insulated actuator
housing. Easy manual operation for initial installation
or emergency operation. Universal electrical connec-
tion by integrated relay.
The signal output of the limit switch in valve position
can be used for control purposes (max. 1 A). The posi-
tion of the ball valve is visible with the white indicator
flag. The actuator can be quickly replaced without di-
sassembling the valve. The DN20 and DN32 versions
offer full bore flow.
