Hydraulic Valves
Control, safety and precision in hydraulic systems
Precision technology for pressure, flow and direction management
Hydraulic valves regulate fluid pressure, flow and direction, ensuring safety, efficiency and control in every application. Fluid System offers a wide range of industrial and mobile valves, designed to ensure rapid response, reliability and long service life even in demanding working conditions.
We work with the leading manufacturers in the sector – Atos, Bosch Rexroth and Tognella – offering modular, integrated and customised solutions for every system requirement. Our multi-brand selection ensures CETOP / ISO compatibility, together with precision and high sensitivity in calibration and testing applications.
Hydraulic Valve range
Solutions for complete control of hydraulic systems
SUBPLATE-MOUNTED VALVES
Characterised by direct mounting on a plate or manifold block, subplate-mounted valves allow flow and pressure regulation in the main circuits, ensuring stable control and system protection. Ideal for hydraulic power units, presses and highly reliable industrial systems.
Brand: ATOS, BOSCH REXROTH
IN-LINE VALVES
Compact and easy to install, in-line valves are suitable for secondary circuits or retrofit applications. They allow flow, sequence and check control in mobile or industrial systems where space is limited. Available with BSP and SAE threaded connections.
Brand: ATOS, BOSCH REXROTH
MODULAR VALVES
Designed to CETOP / ISO standards, modular valves allow stackable configurations to regulate pressure, flow and sequence. They are mounted in packs on manifold blocks and power units, reducing installation and maintenance times.
Brand: ATOS, BOSCH REXROTH
CARTRIDGE VALVES
ISO 7368 cartridge valves, supplied by Atos, allow pressure limiting, reducing and compensation functions directly inside manifold blocks. They offer high flow rates and compact configurations for complex industrial systems.
Brand: ATOS
HYDRAULIC SOLENOID VALVES
Hydraulic solenoid valves electrically control fluid flow and direction in either on/off or proportional mode. Proportional versions from Atos and Bosch Rexroth are the key to digital control and energy efficiency, in line with Industry 4.0 requirements.
Brand: ATOS, BOSCH REXROTH
MINIATURE VALVES
Tognella valves ensure fine flow regulation and precision control in reduced spaces, making them ideal for test benches, laboratories and calibration systems.
Brand: TOGNELLA
COILS AND ACCESSORIES
Original electric coils and accessories ensure compatibility and optimum performance in Atos and Bosch Rexroth solenoid valves. Available in different voltages, protection ratings from IP65 to IP67 and ATEX versions, they include mounting kits, connectors, screws and replacement plugs.
Brand: ATOS, BOSCH REXROTH

FAQ - Hydraulic Valves
CETOP modular and subplate-mounted valves are ideal for hydraulic power units and manifold blocks, thanks to their compact configuration and ease of maintenance.
Proportional valves regulate flow or pressure continuously according to an electrical signal. Servo valves offer higher precision and faster response, typical of high-performance systems such as robotics and test benches.
Yes. Manufacturers such as Atos and Bosch Rexroth offer digital versions compatible with industrial communication protocols.
In many CETOP 3 / 5 / 7 configurations they comply with the same ISO standards, but it is advisable to verify hydraulic compatibility and calibration.
Yes. Our technical department can support you with sizing, pressure selection and matching between Atos, Bosch Rexroth and Tognella components.
