3/2 way solenoid valves
The magnetic 3/2 way solenoid valves of this switching function have a valve inlet, a valve outlet and a venting or return with three connections. The magnetic core is provided with two sealing elements. One pressure port is closed in each case, while two ports are connected to each other. When de-energized, the main flow direction is closed; when energized, it is open.
The de-energized body nozzle is closed, while the pole nozzle for venting & return is connected to the pressure outlet as second body connection. When energized, the pole nozzle is closed, while the two body connections with pressure inlet and pressure outlet are now connected to each other. The direct operated solenoid 3/2 way solenoid valves are manufactured in four different versions in brass and stainless steel.
Solenoid valve – main flow direction closed:
The body nozzle is unblocked and the potting nozzle (venting, return) is connected to the second body connection (pressure outlet).
Solenoid valve energized – main flow direction open:
The potting nozzle is closed and the two body connections (pressure inlet and pressure outlet) are connected to one another.

3/2 way solenoid valves – direct controlled C, normally closed:
Solenoid valves with this circuit function have a valve input, a valve output and ventilation or backflow over three connections. The magnetic core has two sealing elements. At any one time one pressure port is closed while two ports are connected. The main flow direction is closed when the valve is not energised and open when it is. The de-energised body nozzle is closed whilst the potting nozzle for ventilation and backflow is connected with the pressure outlet as a second body port. When the valve is energised, the potting nozzle is closed whereas the two body ports with pressure inlet and outlet are then connected. Directly-controlled 3/2 way solenoid valves come in three different types: C (normally closed), D (normally open), E (multifunction) and F (distributor function).
