Electric solenoid valve two ways

What's the electric solenoid valve?

An electric solenoid valve is a type of valve that uses an electric current to control its operation. It’s typically made up of a coil of wire (the solenoid) that, when energized, creates a magnetic field that drive a iron core to either opens or closes the valve. This type of valve is commonly used in fluid and gas control systems, where automatic or remote control of flow is needed.

Here’s how it works in simple terms:

Coil Activation: When an electric current passes through the solenoid coil, it generates a magnetic field.
Magnetic Force: This magnetic field moves a plunger or piston, which opens or closes the valve seat.
Flow Control: When the valve is open, fluid or gas can flow through the system. When closed, the flow is stopped.

Modern 2 way electric solenoid valve offer fast operation, high reliability, long service life, and space-saving design.

The structure of electric solenoid valve two Ways

1. Pilot Operated

The inner structure

How does electric solenoid valve works?

To Open the Valve:

Energizing the coil creates a magnetic field that actuates the iron core (④), lifting it within the sleeve tube (⑩) to open the pilot orifice (⑦).
This action releases the liquid above the diaphragm through the pilot drain port (⑦), while liquid enters through the diaphragm bleed hole (⑧).
As liquid is released, the pressure above the diaphragm decreases, reducing the force on the diaphragm/piston, which then lifts to open.
Full system pressure on the opposite side of the diaphragm lifts it away from the main valve orifice (⑨), allowing media to flow freely.

To Close the Valve:

When the power is turned off, the magnetic field collapses, causing the iron core to move downward and close the pilot drain port.
Fluid enters the chamber above the diaphragm, raising the pressure until it matches the inlet pressure.
The increasing pressure forces the diaphragm downward, aided by the spring (⑬), closing the valve.

2. Direct Acting

The inner structure

How it works?

To open the valve:

1: When the valve is energized, the coil generates a magnetic force that lifts the plunger (⑨). The plunger moves upward to open the pilot orifice (⑦), while simultaneously lifting the diaphragm bracket (⑥) to open the main valve orifice.

2: The liquid above the diaphragm exits through the diaphragm orifice (⑦), while liquid enters through the smaller orifice (⑬), known as the diaphragm bleed hole.

3: Full system pressure on the opposite side of the diaphragm/piston helps lift the diaphragm/piston away from the main orifice, allowing the full media flow through the valve.

Close the valve:

1. When the power is shut off, the iron core will move downward, closing the Diaphragm Orifice.

2. Fluid will enter the chamber above the diaphragm, causing the pressure to increase until it matches the inlet liquid pressure.

3. The diaphragm is then pushed downward by the force of the spring (3) and downward pressure, closing the valve.

2. Needs minimum pressure differential.

3. Could installed in Higher Pressure system

4. More economical for higher flow values

5. Lower electrical power needed.

6. As utilize the system pressure to open the diaphragm, so need longer response time.

7. In terms of manufacture cost, it’s more economical, as they don’t need the big and expensive coil to actuate.

8. The size is smaller than direct acting valve due to avoid the big and high power coil.

9. As only adopt the low power coil to actuate, it’s more energy efficient!

10. Compared with the direct acting valves, the operate process is more slightly.

11. Widely accepted by the end user and the engineer.

Features of direct acting valves

1. No need the minimum pressure differential when operate.

2. As the valve utilize the coil magnetic force to drive the diaphragm, so more reliable.
