Concrete Pump Solenoid Valve | DG4V-3-6C-M-U-B6-60 | Vickers Type NG6 Valve

DG4V-3-6C-M-U-B6-60 Solenoid Directional Valve for Concrete Pumps

Product Overview: The DG4V-3-6C-M-U-B6-60 is a direct-operated solenoid directional spool valve featuring the global standard Size 3 (NG6 / CETOP 03) interface. As a benchmark of the 60-design sequence, this valve is specifically engineered for rigorous applications such as concrete pumps, construction machinery, and heavy-duty hydraulic power units (HPUs). Its core 6C spool function (3-position, 4-way, P-to-T unloading in center) allows the hydraulic system to dump pressure when idle, effectively reducing energy consumption and system heat generation.

Equipped with a Manual Override (M) and the B6 (high-performance DC coil) optimized for mobile hydraulics, this valve delivers stable and precise flow direction switching under intense vibration and outdoor temperature extremes common to concrete pumping sites.

Key Technical Advantages:

• Engineered for Mobile Hydraulics: Precision-cast from high-strength materials, the valve body handles frequent switching shocks and operating pressures up to 350 Bar.

• Low Pressure Drop Unloading: The 6C logic facilitates oil flow from the pressure port (P) directly to the tank (T) in the center position, significantly enhancing thermal management for pumping systems.

• Wet-Pin Solenoid Architecture: Armatures operate fully immersed in hydraulic oil for superior self-lubrication and heat dissipation, resulting in smooth actuation and an extended mechanical service life.

• Rugged Electrical Interface: Designed with industry-standard connectors featuring high vibration and dust resistance, ensuring reliability in harsh construction environments.
