Hydraulic directional control valves up to 90 l/min – high performance and work dynamics

This subcategory includes advanced hydraulic directional control valves designed to work in systems with increased flow rates, reaching up to 90 l/min. These components are dedicated to medium and heavy-duty machinery, including higher-lift agricultural tractors, excavators, telehandlers, and advanced forestry machinery. Higher throughput allows for faster movement of large oil volumes, which directly translates into shorter cycle times and higher machine efficiency.

The construction of directional control valves in this standard has been reinforced to handle higher hydrodynamic forces occurring at maximum flow without failure. These products are an integral part of our offer in the category hydraulic directional control valves. To ensure full control over operating parameters in such demanding systems, it is essential to use professional pressure gauges and measuring sets. To guarantee installation tightness with larger hose diameters, we recommend using our certified industrial connectors high throughput.

Technical characteristics

Directional control valves with a flow rate of 90 l/min are designed with the minimization of internal resistance in mind. Thanks to the use of wider oil channels and precise spool machining, pressure losses have been reduced, which prevents oil overheating during long operating cycles. This is crucial in systems equipped with high-performance pumps.

Key features:

• Increased throughput: Design optimized for smooth flow of large amounts of medium while maintaining pressure stability.
• High mechanical resistance: High material density casting, resistant to material fatigue under pulsating pressure changes.
• Compatibility with large actuators: Ideal for operating large hydraulic cylinders and high-displacement motors.
• Control versatility: Full compatibility with mechanical, cable, and electric control modules (high-power coils).

FAQ – Technical questions

1. Can a 90 l/min directional control valve be used in systems with a lower flow rate?
Yes, this is permissible; however, proper setting of the relief valve must be kept in mind. Using a control valve with higher throughput in a small system is often done to reduce hydraulic resistance and improve oil cooling.

2. What should be considered when choosing the hose diameter for 90 l/min?
At a flow rate of 90 l/min, the oil velocity in the hoses must be maintained within a safe range (usually 4-6 m/s for pressure lines). Too small hose diameters will lead to large pressure drops and cavitation.

3. Will this directional control valve work in machines with an LS (Load Sensing) system?
We offer 90 l/min directional control valve versions adapted for both constant displacement pump systems and versions with a compensation valve for Load Sensing systems. Please verify the specifications of the specific model.
