The **Vickers DG4V-3-6C-M-W-H-40 4/3 Solenoid Valve (24 VDC, D03, NG06)** is a high-performance, electrically actuated directional control valve engineered for precision hydraulic applications where reliability, efficiency, and compact design are paramount. Part of Vickers renowned **DG4V series**, this **4/3-way, normally closed (NC) valve** is specifically tailored for use in mobile, industrial, and off-highway machinery, offering seamless integration into hydraulic systems requiring robust control of fluid flow. The **24 VDC power supply** ensures compatibility with standard electrical systems, while the **D03** designation indicates a **direct-acting, pilot-operated design**, providing rapid response times and minimal power consumption during operation. The **NG06** port configuration with a **40 mm (1.57 in) port size** delivers optimal flow rates, making it ideal for medium-duty hydraulic circuits where precise directional control is essential, such as in excavators, loaders, or agricultural equipment.
Constructed from **high-strength steel and reinforced components**, this valve is built to withstand harsh operating conditions, including exposure to dust, moisture, and temperature fluctuations, ensuring long-term durability. The **4/3-way spool mechanism** allows for three distinct positions: **center blocked (NC), left pilot, and right pilot**, enabling full control over hydraulic actuators with minimal internal leakage. The **M-W-H** designation signifies a **medium flow rate, wet pilot operation, and hydraulic pilot control**, respectively, further enhancing its versatility in systems where pilot pressure is derived from the main hydraulic circuit. The **integrated magnetic coil** is designed for efficient energy use, with a **24 VDC power requirement** that aligns with standard industrial electrical systems, reducing wiring complexity and improving system reliability.
One of the standout features of this valve is its **compact yet robust construction**, which allows for easy installation in tight spaces while maintaining high performance. The **sealed internal components** prevent contamination from entering the valve body, ensuring consistent operation even in dirty or abrasive environments. Additionally, the **quick-connect fittings** (NG06) simplify assembly and disassembly, reducing maintenance downtime. Vickers reputation for **precision engineering** is evident in the valve s **low friction spool design**, which minimizes wear and extends service life, while the **integrated pressure relief mechanism** protects the system from excessive pressure spikes. Whether deployed in **construction machinery, material handling equipment, or specialized industrial applications**, this solenoid valve delivers **consistent, repeatable performance** with minimal maintenance, making it a trusted choice for engineers and operators demanding both efficiency and durability.
