Solenoid Valve main functions

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.

Three-way, Direct Operated Valves, N/C

Direct operated solenoid valves with a stainless steel or brass body and NBR rubber seals. Fitted with a manual override and suitable for use with air, inert gases oil and water. ASCOs 314 series solenoid valves provide a compact solution for controlling single-acting actuators or filling and draining systems.
