DBE/DBEM valve is a pilot-operated proportional relief valve with poppet valve structure, which can steplessly adjust the pressure of the system according to the input signal.
The valve mainly consists of a pilot valve ① with an electromagnet (2) and a main valve (3) with a main spool (4).
Type DBE:
When the system pressure acts on the main spool (4), it acts on the upper end of the main spool and the pilot valve spool (6) through the damping (5). If the system pressure rises above
When the pressure value is set by the proportional solenoid, the pilot valve poppet valve (6) is opened to control the oil return to the oil tank, and a pressure drop is generated on the main spool (4), so that the main spool is opened, and the pressure oil
From cavity A to cavity 8. Different pressure levels can be obtained by changing the diameter of the pilot valve seat.
Type DBEM:
This type of valve is the same as the DBE type except that there is a maximum pressure protection device to protect the system from damage caused by accidental high pressure.
DBE/DBEM proportional valve has simple structure, good repeatability and linearity of installation and debugging, and strong flow capacity. Widely used in machine tools, light industry, metallurgy, etc.
each field.
Precautions:
1. The media used in the hydraulic system must be filtered; the filtration accuracy is at least 20μm
2. The oil tank used in the hydraulic system must be sealed; and an air filter should be added.
3. Our products do not come with a bottom plate when they leave the factory. (please order if needed)
4. Please select the fixing bolts according to the parameters listed in the sample.
5. The surface roughness requirement for connecting with the valve is 98.
6. The flatness of the connection with the valve is required to be 0.01/100mm
