Solenoid valve (Electromagnetic valve) 9301204 – 3/2 way; G 1/8; Dy 1.6 mm with direct action produced from stainless steel

The electromagnetic valves of this type are devices providing by means of electromagnetic drive control of flowing and stopping of fluid on the pipelines. In the automatic regulation systems they serve as relay bodies for remote control and regulation. The electromagnetic valves are intended for integration in automatic systems in machine building, energy, chemical industry etc. The electromagnetic valves of these series are three-way, two-positioned, normally closed, with direct effect.

3/2-way solenoid valve has three ports (inlet, outlet, and exhaust) and two positions, commonly used to control the flow of fluids (gases or liquids) in a single-acting pneumatic system.

Function and Operation

The “3/2” designation refers to the valve’s configuration:

• 3 Ports: Inlet (P, 1), Outlet (A, 2), and Exhaust (R, 3).
• 2 Positions: The two distinct flow paths the valve can take.

The operation involves an electromagnetic coil (solenoid) which, when energized, moves an armature to change the valve’s position.

• Normally Closed (NC) Function: In its default, de-energized state, the inlet port is closed (blocked), and the outlet port is connected to the exhaust port. When energized, the inlet port opens to the outlet port, and the exhaust port is closed.
• Normally Open (NO) Function: In its default, de-energized state, the inlet port is open to the outlet port, and the exhaust port is closed. When energized, the inlet port is closed, and the outlet port connects to the exhaust port.

Applications

3/2-way solenoid valves are versatile components found in a wide range of industrial and commercial applications:

• Controlling single-acting cylinders: A primary application where the valve fills or vents the air chamber.
• Blow-off and pressure release systems: Ideal for quickly releasing pressure in a controlled manner.
• Vacuum applications: Used to create or break a vacuum seal, such as in pick-and-place operations in robotics.
• Pilot valves: Often used as pilot valves to control larger, more complex process valves.
