ESBE 3F Series Mixing Valve
OPERATION
The ESBE series F is a valve made of cast iron for use in heating and cooling
installations.
The mixing proportions are adjusted manually with a handle or, in
automatically controlled systems, by means of an actuator. Suitable actuators
are ESBE series ARC300 or series 90. The valve can also be equipped with ESBE
controllers series 90C and CRA120.
Valve series 3F is available in dimensions DN 20-150 with flanged connections.
The scale is graded on both sides and can be turned, allowing a choice of
mounting positions. Operation
angle = 90°.
SERVICE AND MAINTENANCE
All major parts are replaceable. The shaft seal consist two o-rings, one of which can be replaced without the need for draining down the system or dismantling the valve. However, before doing so, the system must be depressurized.
INSTALLATION EXAMPLES
All the examples of installations can be reversed. The valve position plate is graded on both sides and should at the installation be fitted in the correct position as shown in the instruction for installation.

VALVE CHARACTERISTICS
DIMENSIONING
HEATING SYSTEMS (RADIATOR OR UNDERFLOOR HEATING SYSTEMS)
Start with the heat demand in kW (e.g. 200 kW) and move vertically to the
chosen ∆t (e.g. 10°C).
Move horizontally to the shaded field (pressure drop of 3-15 kPa) and select
the smaller Kvs-value (e.g. 60).
A mixing valve with a suitable Kvs-value will be found in the respective
product description.
OTHER APPLICATIONS
Make sure maximum ∆P is not exceeded (see line D in the graphs below). ©
