SIEMENS SKP 15.000 E2 GAS VALVE
DESCRIPTION OF HOW THE
VALVE OPERATES
Single-stage valves
When the valve receives the si-
gnal to open, the pump cuts in
and the magnetic valve closes.
The pump transfers the oil from
under the piston to above it, for-
cing the piston downward, whi-
ch compresses the closure re-
turn spring with the rod and plate.

INSTRUCTIONS FOR SETTING
The valve remains in the open po-
sition while the pump and magnetic
valve remain powered.
When the unit receives the signal
to close (or if power supply is cut
off) the pump shuts down, the ma-
gnetic valve opens decompressing
the chamber above the piston.

than 0.6 seconds.
This type of valve cannot regulate
the gas flow rate (closure/ope-
ning).
