BURKERTBaldor solenoid valveIt is also characterized by its flow path or circuit function. Solenoid valves can open, close, distribute, or mix fluids of this type. To better understand the solenoid valve circuit function, you must first look at the standardized solenoid valve symbol.

ISO, or the International Organization for Standardization, is the global federation of standardization bodies. In collaboration with the IEC (International Electrotechnical Commission), they developed symbol standards and rules for the design of fluid power symbols for use in component and circuit diagrams. The standard is ISO 1219.

In the symbol above, the green box indicates the number of valve positions. Arrows, on the other hand, indicate the direction of flow. Blue arrows indicate pressurized flow, while red indicates exhaust. The purple T-wire is the closed port.

The following are common solenoid valve types classified by circuit function.

Two way solenoid valve

This type of solenoid valve has an upstream port and a downstream port to stop or allow fluid flow. Solenoid valve can be configured to normally open and normally closed; Normal state: power off. The normally open valve opens when the power is off and closes when the power is on. Normally closed valves are the opposite.

Three-way solenoid valve

The three-way solenoid valve has three ports: inlet (pressure port), exhaust and outlet (actuator port). These are used to alternately apply and discharge pressure from the actuator or downstream equipment. The three-way solenoid valve can also be configured as normally open and normally closed, increasing the general function. For normally open three-way valves, when the valve is powered off, the fluid flows from the inlet to the outlet, while the exhaust port is closed. When powered on, the air inlet is closed, and the air outlet is connected to the exhaust port. Normally closed valves are the opposite. On the other hand, the universal function is used to select the flow direction from one port to another.

Four way solenoid valve

The four-way solenoid valve has four ports: inlet (pressure port), two outlet or actuator ports, and one exhaust port. Some designs have two exhaust ports. In this type of configuration, there is no normally open or normally closed. Traffic flows either to the first exit port or the second exit port.

Note: These types of valves, whether two-way, three-way or four-way, can act directly or indirectly.
