This multi-section hydraulic Directional Valve, popularly known as the "Hornman", is designed for advanced applications requiring precise control of multiple cylindermi at the same time (" one-in-three" control system). It is ideal for loaders, HDS and construction and agricultural machinery.

The Function Description and Section Configuration (2x Joystick + 2x Lever)

Hydraulic Directional Valve has been configured uNIkalny to minimize the number of manipulators, making the operator's work easier and faster.

Section Configuration:

✅ Sections 1-3 (first, second, third sections): Control by Joystick 1 (Control 1 by 3).

Practical use: Ideal for front loader operation (lift, tilt, implement)

✅ Sections 4-5 (fourth, fifth sections): Controlled by standard Levers.

Practical use: Two independent traditional sections for additional attachments. Features spring-loaded return

✅ Sections 6-8 (sixth, seventh, eighth sections): Controlled by Joystick 2 (Control 1 by 3).

Practical Use: Useful for controlling grab, plow or other advanced attachments

Features Action:

Spring Return: All sections have a spring return to the neutral (0) position for safety and precision

O-Type Spool (Closed Center): The chokes are "O" type

This means that in the neutral position they block the flow of oil to the cylinders and prevent them from moving on their own under load.

Application: Hydraulic Directional Valve for demanding machines

With its advanced 8-section design and one-in-three control system, this hydraulic Directional Valve is designed for the most demanding applications where precision, ergonomics and the ability to control several functions simultaneously are important:

• Front Loaders (Front loader )and Telescopic Loaders: For full control of attachments and main machine movements.
• HDS (Hydraulic Cranes) and Mobile Cranes: For precise positioning of the arm and boom.
• Construction machinery: Backhoe loaders, drilling rigs, earthmoving equipment.
• Agricultural machinery: Combines, balers, harvesting machines with multiple working sections.
• Municipal machinery: Snow plows, spreaders and other specialized vehicles.

WHY CHOOSE THIS Hydraulic Directional Valve? COMPETITIVE ADVANTAGE

• Ergonomics of the "Hornblower" System: Two joysticks controlling 6 sections are a great convenience for the operator, allowing intuitive and fast operation
• High Pressure and Efficiency: Maximum working pressure of 315 Bar and flow rate of 50 L/min guarantee reliability in the toughest conditions
• Serial Connectivity: The built-in N (Carry-Over) port allows another hydraulic Directional Valve to be connected in series, allowing for easy system expansion
• Durable Construction: Phosphate-treated body, and galvanized valves and bolts for long life and high corrosion resistance
• UNIversatile Threads: Standard G1/2" and G1/4" connections make it easy to install into most existing plumbing systems
