Hydraulic directional control valves for open systems 60 l/min 

Hydraulic control valves with a nominal flow rate of 60 l/min are designed to support power hydraulic systems where a proper balance between pump efficiency and actuator speed is required. The sectional design allows for flexible system configuration by adding further work modules, enabling independent control of multiple cylinders or hydraulic motors within a single machine. These devices are adapted for operation in installations with fixed displacement pumps, handling medium flows in Open Center systems. Precise manufacturing of the control spools minimizes pressure losses and uncontrolled internal leaks, resulting in high energy efficiency of the system.

Application and technical characteristics

These components are used in agricultural, forestry, and construction machinery, as well as in stationary industrial equipment where precise operation with high oil flows is essential. The devices are designed for operating pressures up to 250 bar, allowing for safe use in most medium-pressure applications. Bodies made of high-quality ductile iron exhibit high resistance to pressure spikes and material fatigue during intensive operation. The components are fully compatible with hydraulic oils meeting DIN 51524 standards (types HL, HLP), while maintaining a working temperature range for the medium from -20°C to +80°C.

To ensure proper control over operating parameters, we recommend using solutions from the group pressure gauges and test kits, which allow for constant monitoring of the pressure in the system. A safe and tight connection of the control valve with the actuators requires the use of hoses with appropriate capacity, such as 2SN hydraulic hoses, guaranteeing stable operation even under varying loads. In applications requiring remote control, especially in mobile machinery, the optimal technical choice is cable-operated hydraulic control valves, which significantly improve ergonomics and operator safety.

Why choose our components?

• Hydraulic stability: The integrated relief valve protects the system against exceeding the rated pressure, preventing pump failures and hose leaks.
• Modular design: The ability to freely configure the number of work sections ensures easy adaptation of the control valve to modernized machines or those built from scratch.
• High precision manufacturing: Micron-level dimensional tolerances of the spools provide smooth flow regulation and minimize the risk of actuator "jerking".
• Material resistance: High-quality cast body guarantees structural rigidity, which eliminates the risk of housing deformation under maximum load conditions.

Frequently Asked Questions (FAQ)

1. Can a 60 l/min control valve work with a pump of lower displacement?
Yes, this control valve can be used in systems with lower displacement pumps; however, one should remember to properly set the relief valve to avoid unnecessary energy losses on flow through the valve.

2. What should be considered when installing sections with hydraulic locks?
When installing hydraulic locks, ensure the tightness of connections between the control valve and the lock. Locks are required in systems where it is necessary to stop the actuator in a set position when the control valve is off.

3. What are the main differences in spool operation depending on their type?
Spools differ in how ports are connected in the neutral position. Type "A" spools block flow to the actuator, whereas type "B" spools connect both work ports back to the tank, which is important when controlling hydraulic motors.
