Siemens Gas Valves
The gas valves type SKP VG with electro-hydraulic actuators are suitable for the gas families I, II and III (also for air) and are preferably used in gas burner installations.
They open slowly and close rapidly. All valves are fitted with the same compact actuator, which is mounted onto the valve body by means of 4 screws contained in the terminal box.
The square flange can be rotated in steps of 90°, thus proving 4 different mounting positions. The actuator can be mounted or replaced while the valve is under pressure. Sealing material is not required.
Also for control reasons, with burners burning small amounts of gas in low-fire positions and burners that change from high-fire to low-fire in less than 5 seconds the valve size selected must not be too large.
