When installing a 3-way valve check as follows:
Mixture from A/B to AB
Splitting from AB to A/B
4.6 DAMPER
Duct mounted damper with a spring return on/off actuator. The
actuator has to be connected to the terminal block in the electri-
cal cabinet. Size 03 and 04 have circular duct connections and
size 06 has rectangular. The damper is designed for duct insula-
tion of up to 50 mm.
4.7 SILENCER, DUCT MOUNTED
Size 03 and 04 have circular duct connections and size 06 has
rectangular. Fire resistance rating EI30. The distance to the fan
has to be at least 300 mm.
4. CONNECTIONS
4.4 COOLING COIL, WATER
The cooling coils have circular duct connections with rubber
ring seals. For size 06 a converter from rectangular to circular
is available as an accessory (RDTZ-24). The cooler has to be
installed horizontally and the distance to nearest bend has to be
at least 600 mm. Venting and draining is carried out via the pipe
system. The pipe connection, Ø 22 mm, is located on the outlet
end, is smooth and is intended for a compression fitting. The
drainage tray is in stainless steel and has an R 1/2” connection.
Maximum operating pressure 1.0 MPa and maximum operating
temperature 150° C.
4.5 VALVE AND VALVE ACTUATOR
ACTUATORS FOR HEATING SV1 AND COOLING SV2
Connected to terminal in electrical cabinet. Stroke length 5.5 mm.
Intended for assembly on 2-way and 3-way valves of the type
VVG44 or VXG44.
ACCEPTED INSTALLATION METHODS
VALVE FOR HEATING AND COOLING
The valve and valve actuator can be easily installed without
special tools. A particle filter should be fitted before the valve to
extend its service life.
2-WAY VALVE VVG
The flow is increased by turning the spindle inwards, the flow is
reduced by moving the spindle outwards. Note that the 2-way
valve cannot be used as a 3-way valve.
The flow direction is indicated by an arrow.
ACCEPTED INSTALLATION METHODS
3-WAY VALVE VXG
The bypass is closed by turning the spindle inwards, the bypass
is opened by turning the spindle outwards.
