If the three way valve (TRV20/25) is closed,
a low flow passes through the by-pass valve
(BPV10) so that there is always warm water
in the water coil. This is to provide quick
heat supply when a door is opened but also to
provide a degree of frost protection. Actuator
(SD20) controls the heat supply on/off.
TRV25 is DN25 (1”). The by-pass valve is
DN10 (3/8").
SD20, actuator
on/off 230V~ (soft close)
For control of the water supply. Works on/off.
A 5 second cycle of opening and closing of the
valve prevents sudden pressure changes in
the pipe system. IP40.
AV25, stop valve
The stop valve consists of a ball valve which
is either open or closed and is used to shut off
the flow, when servicing for example.
Water control
VKRD, three-way motor valve with actuator and by-pass valve can be integrated
in the unit.
JVF20/25, adjustment valve
The adjustment valve can be used to finely
adjust or shut off the water flow manually.
The adjusted water flow can be read directly
off the valve. JVF20 has a kv value of 3.5 and
JVF25 has a kv value of 5.5.
AFTRD, anti freeze thermostat
Delivered mounted with capillary wire across
the heating coil. At temperature below
approx. 5 °C the thermostat opens the valve
for full water flow through the coil.
To be supplemented with a suitable
thermostat for control.
