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). © Copyright. Rights reserved to make alterations.
