Oil Research DSG-03 Electromagnetic Directional Valve

Product characteristics

1.Fully imported high-precisionCNCLathe processing, size control, stable quality;
2.60HRCThe above high hardness valve core and high hardness ductile iron valve body are wear-resistant and can operate stably in high-pressure environments for a long time. They have a longer service life in medium and low-pressure environments.
3.Internal ***** flow channel design, suitable for high flow systems, ensures smooth fluid flow, reduces hydraulic oil temperature rise, and improves problems such as hydraulic oil deterioration and decreased efficiency of the main engine.
4.High thrust electromagnet andSWPThe use of high-strength springs ensures smooth operation of the product in high-pressure and high flow environments, and stable performance and long service life during long-term high-frequency operation.
5.A spring washer is specially installed in the installation hole of the valve body screw to prevent deformation of the valve body and inability of the valve core to move due to excessive torque during installation. Reduce the probability of human damage.
6.The internal steel ring blocking plate is designed to be silent, with lower operating noise, meeting the requirements of silent environmental protection.
7.Multiple wiring methods can be equipped with waterproof sealed terminals to isolate external moisture and other contaminants, making electrical connections more reliable and suitable for humid working environments. Multiple wiring methods are equipped with power on action indicator devices, which are easy to connect and have clear power on actions.
8.Can provide low voltage surge(LS)The product greatly improves the safety of use.

Model Description

Main specifications

matters needing attention:

1.

For springless electromagnetic directional valves, horizontal installation must be adopted. Other forms do not have this limitation.

2.

Applicable hydraulic fluid
Oil category

Viscosity and oil temperature
Viscosity range:15—400cSt
Oil temperature range: -15—70℃
Cleanliness standards (very important)
Hydraulic components are highly sensitive to pollutants in the oil, and impurities can easily cause hydraulic valve failure or even damage. The level of pollution should be maintained atNAS 1638-12Within the level. Filtering accuracy ****** in25μmOr use more sophisticated filtering equipment.

3.

If any functional electromagnetic directional valve maintains its switching action for a long time under pressure environment, it is easy to cause oil blockage and result in the valve core being stuck and difficult to operate. Attention should be paid to the need for regular cycles to prevent such phenomena.

4.

For any functional electromagnetic directional valve, one end ****** must be powered off before the other end is powered on. A springless electromagnetic directional valve requires the electromagnetic coil to be continuously energized when one end is activated to ensure proper operation.

5.

For any hydraulic valve, the machining of the installation surface must meet the surface roughness requirements6.3sWithin, flatness0.01mmWithin.

6.

Avoid returning the electromagnetic directional valve to the oil port（TConnect directly to the pipeline that may generate hydraulic shock. At the same time, ensureTThe mouth is always filled with oil.

7.

The recommended torque for screw hole installation is50 ~ 80kgf•cmExceeding this range can easily cause deformation of the valve body, leading to poor operation.
