Manifold Block hydraulic valve manufacturer: why do you want to install the bottom plate

 

 

 

1. Automatic control: control method without manual intervention.

 

2. Hydraulic control: used for pressure control pipe in the liquid pressure control, referred to as hydraulic control or hydraulic action.

 

3. Manual control mechanical control: the control method of shaft, CAM, lever and other mechanical parts, referred to as motor control.

 

4. Electric control: control method using electric state change operation, referred to as electric control.

 

5. Servo control: the given signal on the controlled component is compared with the actual signal, and the control is carried out according to the signal error.

 

6. Pneumatic control: used for pressure control of air in the pressure control pipeline, referred to as liquid control.

 

7. Internal pressure control: provide control fluid from inside the controlled component, referred to as internal control.

 

8. External pressure control: the party that provides the control fluid from the outside of the controlled element is called external control.

 

9. Internal oil discharge: The oil discharge channel is connected with the oil return channel inside the element, so that the oil discharge and oil return flow together, referred to as internal oil discharge or internal oil discharge.

 

10. External oil discharge: the way of discharging oil from the oil discharge port of the component, referred to as external oil discharge or external oil discharge.

Manifold Block solenoid directional valve: Manifold Block hydraulic solenoid directional valve type selection requirements

 

Manifold Block hydraulic solenoid directional valve: As a common hydraulic control component, there are many models and specifications of Manifold Block hydraulic solenoid directional valve. Manifold Block hydraulic solenoid directional valve should be considered in the selection of Manifold block hydraulic control components, Manifold Block hydraulic solenoid directional valve has many specifications and parameters, such as flow, control mode, function, voltage and so on.

 

The following factors should be considered in selection:

 

1. Control mode

 

Manifold Block hydraulic solenoid valve is generally divided into two control modes, electromagnetic and manual, which should be selected according to the convenience of operation and the level of automation of the system.

 

2. Spool function

 

Manifold Block hydraulic solenoid directional valve: The different directional functions of Manifold Block hydraulic solenoid directional valve are realized by different valve core designs. The correct spool function should be selected according to the working requirements of the hydraulic system.

 

3. Start smoothness

 

The starting performance of Manifold Block hydraulic electromagnetic directional valve with different intermediate functions is different. If a cavity of the hydraulic cylinder is communicated with the oil tank in the middle position, it is easy to cause uneven starting because there is no hydraulic oil to play a buffer role when starting.

 

4. Reversing accuracy and smoothness

 

When A port and B port are blocked, the reversing is easy to produce hydraulic impact, but the reversing accuracy is high. When A port and B port are connected with the oil return port, the actuator is not easy to brake during the reversing process, but the hydraulic impact is small;

 

5. Pressure and flow

 

The pressure and flow of Manifold Block hydraulic electromagnetic directional valve should meet the following requirements:

 

The working pressure and flow rate of the system should be less than the rated working pressure and flow rate of the valve, otherwise it will lead to abnormal action;

 

The rated flow of Manifold Block electromagnetic directional valve is relatively small. When the system working flow exceeds its rated flow, electro-hydraulic directional valve should be selected;

 

The back pressure of the oil outlet T cannot exceed the large allowable value, otherwise it will lead to difficult reversing of the electromagnetic reversing valve;
