What Is Meant By Direct-acting Solenoid Valve?


Solenoid valves are used to increase the degree in most of the varied varieties of electrical plants as well as equipment. The range of various designs that are available easily and enables the Pneumatic Valve to choose the perfect specification which suits your application.

It features some solenoid, that implies an electrical coil including one movable ferromagnetic hub near its centre. That core is known as the plunger. In another area, the position of the plunger will be closed off with small orifice. An electric flow by these coils generates a magnetic field. This magnetic field uses a force at the plunger.

The result of this plunger will be pulled toward that centre of each coil, and the orifice will be opened. The principle of this Solenoid valves are utilised to open as well as close the solenoid valves.

Solenoid valves remain amongst the various used components under gas as well as liquid circuits. Several applications are almost unlimited. For example, some of the advantages of this solenoid valves are compressed air technology, dental equipment, heating systems, industrial automation, sprinkler systems, swimming pools, washing machines, car washing systems & irrigation systems.

Selidiom valves are considered as four kinds of 3-way. Every different type is used for different objects. Mainly the two types of valves include 3-way which are normally closed, as well as 3-way normally open.

 Those two valves change simply through the reality that one should be a normally open door, while the opposite holds one normally closed. When the 3-way valve remains needed for further complex functions, both the 3-way directional control as well as the 3-way multipurpose valve will be used.

What Is Direct-acting Solenoid Valve?

The working principles of direct-acting solenoids are simple. The Festo Flow Control Valves does not utilise a diaphragm – the seal remains part of that moving core – also it remains closed when negative pressure is remaining applied.

That is in opposition to the pilot-operated valve, that needs some pressure to the valve that is to remain closed. The primary components of this direct-acting 2-way valve are the 6013 type, or a coil, and the closing spring, and the valve body cap and also valve body including the seat.

When the direct-acting solenoid valve remains closed normally, then the path of the outlet gate is blocked if no current will be applied to that coil as that closing spring holds the plunger over the valve position. The current to the coil produces to start force, that pulls that plunger as well as the seal toward the spring unit and draws that medium upward. Also, the channel which is opened to the medium will flow through some direct-acting valve.

Advantages of direct-acting solenoid valves are:



  • It is also suited for negative pressure circuits.
  • Direct-acting solenoid valves are very cost-effective and get in compact sizes.
  • 2/2 as well as 3/2 way that are normally open as well as normally closed versions.
  • Miniature versions will be available in high pressures.
