MOTORIZED: A valve that is opened and closed by the action of an electric motor on an actuator PNEUMATIC: A valve that is opened and closed by pneumatic actuation SOLENOID: A valve that is normally held open by a magnetic field in a coil acting on the gate but that is closed immediately if the electrical current generating the magnetic field is removed. SPRING: A valve that is normally held in position by the pressure of a spring on a plate but that may be caused to open if the pressure of the fluid is sufficient to overcome the spring pressure.

    <rdfs:comment xml:lang="en"> Indicates the setpoint and label. For toggle switches, there are two positions, 0 for off and 1 for on. For dimmer switches, the values may indicate the fully-off and full-on positions, where missing integer values in between are interpolated. For selector switches, the range indicates the available positions. An IfcTable may be attached (using IfcMetric and IfcPropertyConstraintRelationship) containing columns of the specified header names and types: 'Position' (IfcInteger): The discrete setpoint level. 'Sink' (IfcLabel): The Name of the switched input port (IfcDistributionPort with FlowDirection=SINK). 'Source' (IfcLabel): The Name of the switched output port (IfcDistributionPort with FlowDirection=SOURCE). 'Ratio' (IfcNormalizedRatioMeasure): The ratio of power at the setpoint where 0.0 is off and 1.0 is fully on.</rdfs:comment>

The corresponding range of colours varies from violet to indigo, blue, green, yellow, orange, and red.

    <rdfs:comment xml:lang="en"> The type of ballast used to stabilise gas discharge by limiting the current during operation and to deliver the necessary striking voltage for starting. Ballasts are needed to operate Discharge Lamps such as Fluorescent, Compact Fluorescent, High-pressure Mercury, Metal Halide and High-pressure Sodium Lamps. Magnetic ballasts are chokes which limit the current passing through a lamp connected in series on the principle of self-induction. The resultant current and power are decisive for the efficient operation of the lamp. A specially designed ballast is required for every type of lamp to comply with lamp rating in terms of Luminous Flux, Color Appearance and service life. The two types of magnetic ballasts for fluorescent lamps are KVG Conventional (EC-A series) and VVG Low-loss ballasts (EC-B series). Low-loss ballasts have a higher efficiency, which means reduced ballast losses and a lower thermal load. Electronic ballasts are used to run fluorescent lamps at high frequencies (approx. 35 - 40 kHz).</rdfs:comment>
