FAQ
Q: What kind of valve is the DSG series, and what is its primary function?
A: The DSG series consists of solenoid-operated directional control valves. They use a solenoid to shift the valve spool and alter the flow direction of the hydraulic fluid, thereby controlling the starting, stopping, and directional switching of hydraulic actuators.
Q: Can both electromagnets be energized simultaneously?
A: No. With a dual-solenoid valve, the two coils must not be energized at the same time; doing so will burn out the coils. You must de-energize one end before energizing the other.
Q: Can the electromagnet coil be replaced separately?
A: Yes. The coil is detachable and replaceable; when replacing it, ensure that the voltage and power match the original specifications.
Q: What should be done if the valve spool sticks?
A: First, check the cleanliness of the hydraulic fluid; if contamination is severe, clean the valve spool and bore, and replace the fluid and filter element. If valve body deformation is caused by excessive mounting bolt torque, retighten the bolts to the specified torque.
Q: What should be done if switching is sluggish or causes significant shock after prolonged use?
A: The issue could be due to hydraulic fluid viscosity being too high or too low, air in the system, or spool wear.
