Burkert Solenoid Valve 143490, 2 port(s) , NO, 230 V ac, 1/2in

The Burkert 0280 series 1/2inG female solenoid valve has a supply voltage of 230VAC. This 2-port NO position valve with a servo diaphragm has a compact design with NBR seal. The valve is normally open by spring action assisted by the fluid pressure. When de-energized, the media is exhausted to atmosphere via the pilot operator. When energized, the space above the servo diaphragm is exhausted via the pilot valve, the diaphragm is lifted by the fluid pressure to close the valve.
Compact solenoid valves suitable for most gas and fluid handling applications. Where practical, valves are shown with a schematic diagram showing the (circuit) function. The diagram is laid out so that the left-hand side of the diagram describes the operation of the valve when the coil is energised. When the coil is de-energised, the spring (or servo-assist) return controls the valve and is described on the right-hand side of the diagram. The 3 / 2-way designation indicates a valve with three ports and two modes of operation. It is normal practice to refer to 2 / 2-way valves as two ways. The port designations A, B, P, P1, P2 and R are used on the schematic diagrams and are marked on the valve bodies. Valve bodies are marked for a specific circuit function but can often be used for other functions. Reference to the schematic diagrams and technical specifications indicates the appropriate connections and pressure capabilities when an alternative circuit function is required.
