Range of solenoid valves 3//2 NF A output, except 439-032 (Function C), with exhaust when off, for neutral liquids up to +100°C.
The solenoid can be positioned freely or locked in 4 positions at 90° intervals.
Able to change the solenoid without removing the valve.
High quality FPM (Viton) sealing material as standard.
DIN 43 650A connector.
Brass body.

3 Way Inert Gases and Fluid Valves

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 valves operation when the coil is energised. When the coil is de-energised, the spring (or servo-assist) return controls the valve and this is described on the right hand side of the diagram, see the typical schematic diagram below.,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-way.,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 will indicate the appropriate connections and pressure capabilities should an alternative circuit function be required.
