Product Features:
The milled throttle groove on the valve spool can accurately control the change in flow rate when the valve spool is switched.
The easily removable throttle plug allows for fine-tuning the switching time of the valve for each application condition.
Standard performance and high-performance solenoids are provided to designers for matching flow rates and tank pressure with the rated system requirements.
The “P12L” type offers a junction box with a rectifier, light, and cartridge coil, allowing for simple and quick replacement of the solenoid without needing to remove the valve from the machine.
Product Advantages：
Save on installation costs and space, with a high power/weight ratio and power/volume ratio.
Less internal leakage, lower power consumption, high system efficiency, improved manufacturing of valve cores and valve holes.
A variety of combinations of solenoid plugs and positions are available for flexible installation.
Suitable for various types of oils without the need to change seals.
More than 20 million cycle tests have confirmed its excellent fatigue life and durability, allowing for high long-term productivity and extended operating time of machines.
The electromagnetic coil can be quickly and easily replaced without causing hydraulic system oil leakage.
Frequently Asked Questions and Solutions
Fault Phenomena DG4V-3-2C Possible Causes DG4V-5-6CJ Possible Causes
Valve spool not moving: Coil open circuit, insufficient voltage, valve spool jammed. Same as above, or insufficient hydraulic positioning pressure.
Excessive leakage: Aging of sealing parts, scratches on the valve body. Same as above, or failure of mid-position sealing function.
Slow switching to three positions: Not applicable (two-position valve). Insufficient electromagnetic attraction, spring fatigue.
Electromagnet overheating: Continuous operation, poor heat dissipation. Same as above, or voltage fluctuations causing frequent starts and stops.
