The traditional choice for hydraulic systems requiring wide market compatibility and easy serviceability worldwide. NG6 directional valves are a reliable solution for many standard applications and are particularly suitable where a conventional valve layout is preferred. Each valve requires a dedicated base modular manifold.

Hydronit offers NG6 sandwich valves for flow control, pressure control and overcentre functions. These solutions allow additional hydraulic functions to be added in a compact modular stack, simplifying circuit design and improving integration on the power unit. An important advantage is the use of the same cartridge logic already adopted in the central manifold range.

Stackable valves are the advanced alternative to conventional spool valves when the objective is to reduce overall dimensions and weight. The A and B threaded ports are directly machined into the valve body, while additional cavities can be used to increase circuit flexibility. This architecture is especially useful where space is limited and multiple valve functions must be combined in a compact assembly.

For applications where low weight, essential design and cost efficiency are priorities, cartridge valves integrated into external blocks represent a practical and effective solution. They allow the hydraulic system to remain compact while ensuring dependable control and easy integration with the Hydronit modular concept.

Hydronit external valves are engineered to support different circuit architectures, from conventional NG6 layouts to more advanced stackable solutions. Compared with traditional Cetop 3 assemblies, stackable and NG3 MICRO-related solutions offer important benefits in terms of reduced size, lower weight and lower cost, making them particularly attractive for compact hydraulic power packs and machines with limited installation space. The catalog also highlights that a stack of seven stackable valves can be significantly more compact than an equivalent NG6 solution.

At the same time, NG6 valves remain the preferred solution when the hydraulic circuit requires additional functions such as pilot operated check valves, pressure controls or flow controls combined in a more traditional modular configuration. This makes the range highly versatile, allowing machine designers to choose between maximum compactness and maximum circuit modularity depending on the application.

• Compact circuit design
  Stackable and cartridge-based solutions help reduce the footprint of the hydraulic assembly, supporting more compact machine layouts.
• Modular configuration freedom
  Different valve technologies can be selected according to the required function, pressure control logic and installation constraints.
• Wide application compatibility
  The range supports industrial, mobile and special hydraulic applications with solutions that integrate with Hydronit power units.
• Reliable integration with Hydronit systems
  External valves are developed to work consistently with Hydronit manifolds, modular blocks and power pack architecture.

Hydronit external valves can be used in many sectors where hydraulic control must be precise, compact and reliable. They are suitable for industrial machinery, mobile equipment, lifting systems and applications where multiple hydraulic functions must be managed within limited space. Their modular approach also makes them a valuable option for OEMs looking for scalable and configurable hydraulic solutions.
