INSTRUCTIONS FOR SETTING
SIEMENS SKP 15.000 E2 GAS VALVE
DESCRIPTION OF HOW THE VALVE OPERATES
Single-stage valves
When the valve receives the signal to open, the pump cuts in
and the magnetic valve closes. The pump transfers the oil from
under the piston to above it, forcing the piston downward, which
compresses the closure return spring with the rod and plate. The
valve remains in the open position 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 magnetic valve opens decompressing
the chamber above the piston. The plate is closed both by the return
spring and by gas pressure. The flow rate for this valve is calculated
to ensure full closure in less than 0.6 seconds.
This type of valve cannot regulate the gas flow rate (closure/ope-
ning).
