160 l/min hydraulic control valves
The offered 160 l/min control valves are devices designed to work in systems where flow parameters are demanding and pressure stability determines the efficiency of the entire machine. Bodies made of high-grade ductile iron provide the required structural rigidity, which eliminates the risk of deformation during sudden changes in operating pressure, reaching up to 300 bar depending on the model. Precise fitting of spools in the bores allows for minimizing internal leakage, which translates into effective energy management in the system. In systems with such high efficiency, it is necessary to use high-class hydraulic filters, which protect working elements against degradation caused by particulate contamination.
These devices are suitable for operation with hydraulic oils with kinematic viscosity according to DIN 51524 standards. The thermal resistance of the seals allows for continuous operation at working medium temperatures from -20°C to +80°C. Standard threaded connections ensure the tightness of connections at high flow rates, and optional floating sections or hydraulic locks allow for the configuration of the control valve for specific machine requirements. In case of the need to expand the system with rigid steel pipes, we recommend our pipe and hose clamps, which eliminate harmful vibrations occurring during high-flow operation.

FAQ – most common technical questions
- Should an oil cooler be used at a flow rate of 160 l/min?
- In the case of long-term operation under maximum load, heat energy dissipation becomes important. If the heat balance of the system exceeds 80°C, installing a cooler is recommended to maintain the oil's viscosity parameters.
- Does this control valve work with Load Sensing pumps?
- We offer versions adapted for operation in Load Sensing (LS) systems, which via a signal line regulate the pump output only when needed, significantly increasing fuel economy.
- What are the requirements for oil cleanliness?
- It is required to maintain the oil cleanliness class according to the ISO 4406 standard (recommended 18/16/13). Regular replacement of filter elements is the basis for the durability of the control spools.
