Direct-acting 3/2-way Solenoid Valve

Direct-acting 3/2-way Solenoid Valve

Function:
The functioning principle of the direct-acting 3-way plunger valve depends on how the fittings are connected to the fluid system. As opposed to the 2-way plunger valve it has two valve seats and one return flow. If no electric voltage is present, a normally closed 3/2-way valve allows no passage from the pressure connection P to connection A (outlet), since a conical spring presses the plunger onto valve seat 1. At the same time, A is directly connected to R (return flow) and valve seat 2 is opened. If the coil is energised the plunger is pulled in and seals valve seat 2. The path between A and R is therefore blocked. At the same time valve seat, 1 is opened and the channel between P and A is opened for the medium.

Application:
These valves can be used in diverse applications, such as mixing, distribution, ventilation, dosing, etc. of neutral gaseous and liquid media. This type is frequently used as a pilot valve for larger pneumatically actuated valves. Special features: Special features of this valve type are the convenient, service-friendly manual override, the energy-saving pulse design and its suitability for use in explosive areas. In addition, there are versions that are suitable for high-temperature media (hot water, hot air and steam).
