AVENTICS 2-Position 3-Way Directional Control Valve Working Principle

The 6-way directional control valve mainly consists of a valve body, sealing components, cam, valve stem, handle, and valve cover (Figure 1). The valve is driven by the handle, which rotates the valve stem and cam. The cam has the functions of positioning, driving, and locking the opening and closing of the sealing components. When the handle is rotated counterclockwise, the two sets of sealing components close the two lower channels under the action of the cam, while the two upper channels are connected to the inlet of the pipeline device. Conversely, the two upper channels are closed, while the two lower channels are connected to the inlet of the pipeline device, achieving non-stop directional switching.

Solenoid valves have the most specifications, mainly including the following:

1. Operational reliability

This refers to whether the solenoid can reliably switch directions when energized and reliably reset when de-energized. Solenoid valves can only operate normally within a certain flow and pressure range. The limits of this operating range are called the switching limits.

2. Pressure loss

Because the opening of the solenoid valve is very small, a significant pressure loss occurs when the fluid flows through the valve port.

3. Internal leakage

The amount of leakage from the high-pressure chamber to the low-pressure chamber at various operating positions and under the specified operating pressure is the internal leakage. Excessive internal leakage not only reduces system efficiency and causes overheating but also affects the normal operation of the actuator.

4. Switching and Reset Time

The switching time of AC solenoid valves is generally 0.03–0.05 seconds, with a relatively large switching impact; while the switching time of DC solenoid valves is 0.1–0.3 seconds, with a smaller switching impact. The reset time is usually slightly longer than the switching time.

5. Switching Frequency

The switching frequency is the number of times the valve is allowed to switch per unit time. Currently, the switching frequency of single-electrode solenoid valves is generally 60 times/min.

6. Service Life

The service life of a solenoid valve mainly depends on the solenoid. Wet solenoids have a longer service life than dry solenoids, and DC solenoids have a longer service life than AC solenoids.

7. Hydraulic Jamming of Spool Valves

Hydraulic jamming of spool valves is not only present in directional valves but also commonly occurs in other hydraulic valves, and is more prominent in high-pressure systems. Especially, the longer the spool valve's dwell time, the greater the hydraulic jamming force, to the point that the thrust of moving the spool valve (such as the solenoid's thrust) cannot overcome the jamming resistance, preventing the spool valve from resetting.

Hydraulic jamming can be caused by various factors, including contaminants entering the gaps and hindering valve core movement, or by excessively small gaps causing valve core expansion and jamming due to increased oil temperature. However, the primary cause is radial unbalanced hydraulic pressure resulting from geometric errors and concentricity variations in the spool valve assembly. To reduce radial unbalanced forces, the manufacturing precision of the valve core and valve bore should be strictly controlled. During assembly, they should be made as conical as possible. Additionally, adding annular pressure-equalizing grooves to the valve core can significantly reduce radial unbalanced forces. [2]
