Lever-operated hydraulic directional control valve with a flow rate up to 50 l/min
Hydraulic directional control valves with a nominal flow of 50 l/min are versatile control units dedicated to mobile and stationary hydraulic systems that require higher efficiency while maintaining precision of operation. These devices are a key component of the circuit, responsible for directing the oil flow to actuators and motors with higher flow rate requirements. Thanks to a robust lever-based design, the operator gains direct control over the machine's movement dynamics, which is essential in demanding agricultural and industrial applications.
Design and work efficiency
The valve block is cast from ductile iron, ensuring high rigidity even at a maximum operating pressure reaching 250 bar in the working ports. The device is designed for a long life cycle while maintaining stable hydraulic parameters in variable environmental conditions. Operation across a wide temperature range – from -20°C to +80°C – makes it an ideal component for year-round machinery.
To ensure trouble-free operation of the spools, it is essential to use effective filler filters, which prevent contaminants from entering the tank during fluid replenishment. Equally important for system integrity is the use of durable hydraulic hoses, which will easily withstand a flow of 50 l/min without causing excessive pressure drops. If complex connections are required, we encourage you to check our offer for hydraulic adapters, which allow for the seamless connection of different thread standards.
Why choosing our valves ensures reliable operation?
Our 50 l/min valves are characterized by high spool operation quality, which are precisely fitted to the seats, minimizing oil loss through internal leakage. The integrated relief valve allows for accurate adjustment of the maximum system pressure, which directly protects the pump and actuators from overload. The design allows for easy system expansion – simply use the appropriate tie rods for valves to add more working sections if necessary. In emergencies or during maintenance, the availability of hydraulic valve parts allows for quick restoration of full machine functionality without incurring the cost of replacing the entire block.

FAQ – service and operation
1. Does the 50 l/min valve require special installation?
The valve should be mounted on a flat surface to avoid body stress that could hinder smooth spool operation. It is also important to ensure free oil flow to the T port.
2. What to do when the lever offers resistance?
Resistance can be caused by oil that is too thick at low temperatures or the presence of contaminants in the lever channel. If the problem disappears after the oil warms up, it is worth checking if the used hydraulic oils have the correct viscosity for the given season.
3. What are the causes of oil leaks under the levers?
Leaks are most often the result of seal wear due to abrasion (contaminants in the oil). If you observe a leak, we recommend professional service of the device to avoid further degradation of the spool mechanism.
