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/opening).
