The on-off valve
A solenoid valve is a valve which is actuated by a solenoid. These valves can switch very quickly, depending on type.
Solenoid valves generally consist of a solenoid part and a valve part. When the solenoid switches, components in the valve are actuated by the armature.
Valves control the inlet or outlet of fluids or control and regulate the direction of flow.
The direction of flow can be controlled by directional valves. These valves include the 3/2-way valve or the 5/2-way valve, for example.
In the case of directly controlled valves, the sealing element switches directly via the solenoid system.
Pressure-controlled valves are controlled through an external pilot valve. This means that high temperatures, high pressures, contaminated media, aggressive operating material, etc. can be controlled with clean control medium.
2/2-way valves, also called glove valves, are shut-off valves with an inlet and an outlet. The neutral position (solenoid de-energized) can be both open and closed. The flow rate is blocked and released through switching of the solenoid.
3/2-way valves have three connections and two ball seats. These valves have one connection for the pump (P), one connection for the tank (T) and one working connection (A). In de-energized state, connection A is connected to connection P and to connection T. Through switching of the solenoid, the working connection (A) can be connected to the next closed connection.
