221633, 3/4" Solenoid valve 20 mm
|12 420||×||=||12 420|
Burkerts new range of 2 way normally closed solenoid valves. Manufactured from brass and designed for use with water and inert liquids and gases. A soft mechanical coupling between the main piston and pilot armature aids smooth operation and a precision engineered main body path helps ensure quiet, water hammer free operation.
Suitable for a diverse range of applications including compressed air and vacuum systems, heating and refrigeration, water treatment and swimming pool technology. Compact size to aid installation when space is limited
0-10 bar operating pressure
0.1-4 second response time
Opens without differential pressure
Minimum pressure differential of 0.5 bar for full opening
High flow rate
Due to their internal complexity these valves can only be used with clean neutral media
Two 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 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.
Solenoid Valve main functions
Range of solenoid valves suitable for most liquid or gas applications.
Each valve is delivered with an individual operational schematic.
The left section of the schematic shows valve behaviour when the coil is energised.
When the coil is at rest, the valve is controlled by the return spring (or servomechanism). This phase is depicted in the right section of the schematics.
Port descriptions A; B; P; P1; P2 and R are used in the schematics and are marked on the valve bodies. The three-way valve bodies are suited to specific tasks, but may also often be used for other tasks.
References in the operational schematics and various technical characteristics describe the appropriate connections and allowable pressures for valves being used for different tasks.
