Proportional Cartridge Directional 2/2 Way Valves - Normally Closed

These valves are a subcategory of cartridge valves, installed directly into hydraulic manifolds or blocks for compact and efficient circuit design.

Key features include:

• Proportional control – allows variable flow adjustment rather than simple open/closed states.

• Normally closed configuration – blocks flow until actuated, ensuring secure load holding.

• Directional function – controls fluid path between two ports (inlet and outlet).

• Compact cartridge format – reduces external piping and simplifies installation.

• Smooth operation – enables precise actuator movement and improved system efficiency.

• Precision control – proportional actuation allows fine adjustment of flow.

• Load-holding capability – prevents unintended actuator movement until commanded.

• Secure default state – “normally closed” ensures fluid is blocked unless the valve is actuated.

• Compact integration – fits directly into manifolds for space-saving design.

• Reliable performance – suitable for demanding mobile and industrial environments.

These valves are widely used in:

• Mobile machinery (construction, agriculture, forestry)

• Industrial automation and process control

• Marine and offshore hydraulic systems

• Energy and utility installations

• Material handling and lifting equipment

They are particularly valuable in systems requiring secure blocking with precise proportional control.

We source proportional cartridge directional valves from a wide network of manufacturers, including:

Hydraforce… and many more

As an independent supplier, we provide unbiased recommendations based on your system’s needs – not a manufacturer’s catalogue.

What does “normally closed” mean? It means the valve blocks fluid flow in its default state and only opens when actuated.

How do proportional valves differ from standard directional valves? Standard valves operate in simple open/closed states, while proportional valves allow variable flow control.

Are proportional valves suitable for load-holding applications? Yes, their normally closed design makes them ideal for holding loads securely until actuated.

Can these valves be integrated into manifolds? Absolutely. Their cartridge format is designed for compact manifold installation, reducing external piping.
