Hydraulic control valves for closed-center systems: Flow rate 90 l/min

Hydraulic control valves with a capacity of 90 l/min are advanced control units dedicated to machines requiring higher operational power, such as professional forestry equipment, backhoe loaders, or industrial machinery. They are designed to work in "closed center" systems, where they provide precise control of hydraulic functions in cooperation with variable displacement pumps. To protect such efficient systems from premature wear, we recommend using professional hydraulic filters with appropriate filtration accuracy.

Technical characteristics and application

Devices of this class are characterized by a solid body construction made of ductile iron, allowing for safe operation under high working pressure. Precise fitting of control elements guarantees high responsiveness and minimization of energy losses. If there is a need to replace seals or minor components during machine service, we invite you to browse our hydraulic control valve parts. The models we offer are fully compatible with a wide range of products available in the category hydraulic control valves.

Frequently Asked Questions (FAQ)

Will a 90 l/min control valve work in a forestry machine?
Yes, it is the optimal capacity for forestry cranes and harvesters, where fast and smooth control of multiple receivers simultaneously is required.
What are the benefits of the closed center system in this model?
Closed center systems allow for better control over system pressure and significantly reduce fuel consumption by working with variable displacement pumps.
