DCG Directional Valve OVERVIEW

DCG directional valve is mechanically cam‑actuated hydraulic directional control valve. It adopts threaded port connection and spring‑return reset structure. Spool movement is driven by external mechanical cam mechanism instead of manual lever or solenoid. It achieves automatic oil‑flow direction switching following mechanical motion. Compact structure, reliable mechanical actuation, widely used for industrial and mobile hydraulic equipment.

Features and Benefits

• Cam‑driven mechanical actuation, triggered by external machinery movement, no manual or solenoid operation required

• Spring‑return structure, automatically resets spool position when cam force disappears

• Optimized internal flow passage, low pressure loss, stable flow performance

• Threaded port connection, easy installation and maintenance

• Solid valve body construction, good shock‑resistance, suitable for vibrating working conditions

• Compatible with standard mineral hydraulic oil; special sealing materials are available for special media

DCG Directional Valve FAQ:

1. What is the DCG Directional Valve ?

DCG directional valve is cam‑actuated mechanical hydraulic directional control valve with threaded ports. It works by external cam pushing the spool to realize oil‑flow switching, and returns to initial position by spring force after cam force disappears. It requires neither solenoid power supply nor manual lever operation. Compact threaded‑port structure, good vibration resistance. It is commonly used in industrial and mobile hydraulic systems for automatic directional switching triggered by mechanical travel motion.

2. What makes the DCG Directional Valve ?

3. What is the working pressure range of DCG Directional Valve ?

For DCG directional valve, the maximum working pressure for P/A/B ports is 31.5 MPa, and the maximum allowable back‑pressure at T return port is 16 MPa. It maintains stable performance under rated pressure in industrial and vibration‑prone mobile hydraulic systems.
