SIEMENS VGF10.654P-DN65 gas valve

SIEMENS VGF10.654P-DN65 gas valve

On / off safety shut-off valves, 2-stage or with integrated constant or balanced
gas pressure governor; for natural gas, town gas or liquefied petroleum gas in
the low pressure range.
Electrohydraulic actuators featuring delayed opening and rapid closing.
The SKP1… / SKP2… / VG… and this Data Sheet are intended for use by OEMs
which integrate the actuators and gas valves in their products.

The VG… gas valves with their electrohydraulic SKP… actuators are designed for gas
families I, II, III and air. They are used primarily in gas-fired combustion plant. The
valves open slowly and close rapidly. All types of VG… gas valves can be combined
with the available types of actuators. The actuator is fitted to the valve body by means
of the 4 screws contained in the terminal compartment. The square flange can be
turned in steps of 90°, thus providing 4 different mounting positions. The actuator can
be fitted or replaced while the valve is under pressure. Sealing materials are not required.
Actuator type SKP2… is equipped with an integrated precision gas pressure
governor. This type of actuator with gas pressure governor not only reduces the length
of the gas train, but usually also permits selection of a smaller valve size. For detailed
information about valve sizing, refer to «Flow chart». The actuator is also available with
limit and auxiliary changeover switches, e.g. for indicating the fully closed position or for
stroke limitation in connection with 2-stage gas release, etc.
The SKP20.130… operates as a balanced gas pressure governor and controls the gas
pressure according to the pressure of the combustion air so that the gas / air ratio remains
constant over the entire load range (shifting the setpoint by the static pressure of
the combustion air).
Therefore – in contrast to conventional gas / air ratio control – air volume changes due
to mains pressure variations, soiled fan wheel, etc., have no impact on the quality of the
combustion process.
