Hydraulic directional control valves: manual and electric control (12V/24V)
In power hydraulic systems, the precision and reliability of medium flow control determine the efficiency of the entire machine. We offer advanced monoblock and sectional hydraulic directional control valves, designed to work in high-pressure installations. Our devices allow for smooth management of cylinders and hydraulic motors using ergonomic levers or fast solenoid valves (12V/24V), ensuring full control in agriculture, forestry, and construction.
Key advantages and technical benefits
-
- Precise flow modulation: The use of precision-ground spools minimizes the "jerking" phenomenon when starting and stopping actuators.
- Two coil power supply standards: We offer a full range of 12V hydraulic control valves (dedicated to tractor installations) and 24V hydraulic control valves (for heavy machinery and specialized vehicles).
- High fatigue strength: Bodies cast from high-density ductile iron, resistant to pressure spikes (nominal pressure up to 250 bar).
- System modularity: Design allowing for series connection and easy installation of additional control sections.
- Connection standard: The devices are fully compliant with BSP standards, which guarantees high connection tightness and easy integration with existing installations. Thanks to universal threads, the user can quickly optimize the system configuration by using the necessary hydraulic valve nipples, choosing dedicated hydraulic quick couplers or expanding the control system with professional valve sections, which significantly reduces machine downtime during maintenance.

FAQ: Frequently asked technical questions
What are the main differences between 12V and 24V electric control? The difference stems solely from the solenoid coil's supply voltage. The voltage choice must be strictly correlated with the machine's electrical installation. Using 12V coils in a 24V installation will lead to them burning out, while 24V in a 12V installation will not generate enough magnetic force to move the spool.
Can monoblock valves be serviced? Yes, our valves have replaceable spool seals and replaceable electric coils, which allows for full regeneration without the need to replace the entire block.
How to correctly calculate the required valve capacity? The valve capacity (l/min) should always be 10-20% higher than the maximum capacity of the hydraulic pump to avoid excessive flow resistance and oil overheating in the system.
