Lever-controlled hydraulic control valve with flow up to 10 l/min
Monoblock control valves with a nominal flow of 10 l/min form the foundation of control systems in miniature hydraulic equipment. These devices are responsible for directing the flow of the working medium between the pump and actuators such as single-acting or double-acting cylinders. Thanks to their compact design and precise spool fitting, these components ensure stable operation of systems with low oil flow requirements. The use of high-grade construction materials guarantees the repeatability of operating parameters over long-term use.
Application and technical characteristics
The described control units are designed for use in power hydraulics systems with a maximum working pressure up to 250 bar in supply (P) and service (A, B) ports. The valve bodies are cast from high-strength ductile iron, allowing for safe operation under variable mechanical loads. The design is fully compatible with mineral oils meeting the DIN 51524 standard, including HLP and HVLP type fluids. The permissible temperature range of the working medium is from -20°C to +80°C, enabling integration with machines working in harsh environmental conditions. The required oil cleanliness level should comply with ISO 4406 standards, which limits the risk of spool abrasion. To maintain the system in full efficiency, it is necessary to use efficient hydraulic filters on the return line. Standard BSPP threaded connections facilitate quick installation using high-pressure hydraulic connectors.
Why choose our components?
The offered control valves are distinguished primarily by the precision of the control channels, which directly affects the minimization of internal leakage. Each component is subjected to leakage tests at pressures exceeding nominal operating values. Thanks to the standardization of connections, these devices are fully interchangeable with most solutions used in modern agricultural and forestry machinery. High resistance of the body to fatigue cracks and precise relief valves ensure full safety for the operator. In case of servicing needs, the user receives full access to documentation and dedicated hydraulic control valve parts, which significantly reduces maintenance costs.

Frequently Asked Questions (FAQ)
Can a 10 l/min control valve work with a pump with a capacity of 20 l/min?
This is not a recommended solution. Exceeding the nominal flow by 100% causes a drastic increase in pressure losses and excessive heating of the oil, leading to premature wear of seals and degradation of the physicochemical properties of the working medium.
How to choose the correct relief valve pressure?
The valve pressure should be set to the operating value of the system, and it must be lower than the maximum pressure generated by the pump. Adjustment is carried out using a pressure gauge connected to the circuit, in accordance with the requirements of the end receiver.
Does the control valve have a floating function?
A standard monoblock control valve has a "closed" type spool in the neutral position. Versions with a floating function are specialized products that should be selected individually based on the manufacturer's code or the machine's design requirements.
