Standard model
Solenoid valve
with cut-off
- Light oil.
- Nozzle low up to 45 l/h (approx.
460 000 kcal/h - 534 kW).
- One or two-pipe system.
Pump operating principle
The oil pump has a built in solenoid
valve which controls the regulator
cut-off valve giving fast cut-off and
cut-on function independent of the
rotational speed.
The gear-set draws oil from the tank
through the built-in ilter and transfers
it to the valve that regulates the oil
pressure to the nozzle line.
All oil which does not go through the
nozzle line will be dumped through
the valve back to the return line or, if
it is a one-pipe installation, back to the
suction port in the gear-set.
- Two-pipe operation
When the solenoid valve is non-activated,
the by-pass channel between the
pressure and return sides of the valve
is open.
No pressure will then be built up to
open the valve. It does not matter
which speed the gear set has.
When the solenoid is activated, this
by-pass channel will be closed and
because of the full speed of the gear-
set, the pressure necessary to open
the valve will be built up very rapidly
which gives a very sharp cut-on
function.
- One-pipe operation
Bleeding on one-pipe is not automatic,
and a pressure port must be opened
to bleed the system.
Cut-off
When the burner stops, the solenoid
opens the by-pass at the same moment
which drains all the oil down to the return
and the nozzle valve closes immediately.
This gives a very sharp cut-off function.
The cut-on and off can be regulated
regardless of motor speed and has
an extremely fast response.

APPLICATIONS FOR SUNTEC AT2 45C

When the solenoid is non activated,
the torque requirement is low up to
full motor speed.
