Hydraulic Cartridge Valves

These screw-in modular valves control pressure, flow, and direction in compact, high-performance units.
Including relief valve, counterbalance, flow control, check valve, shuttle and directional control valves.
Available in different sizes, their flow capacity doubling with each larger size.

Manifolds house multiple valves in compact configurations: line-mount manifolds, sandwich manifolds, or custom manifolds.
Integrated packages combine standard valves into engineered systems using QuickDesign™ software and SunDesign™ expert services.
These integrated solutions can deliver up to 50% size reduction compared to competing systems due to efficient layout and 5 axis design.

Sun Hydraulics is a leader in merging traditional mechanical hydraulics with advanced electronics. They specialize in electro-proportional cartridge valves and digital control systems that allow for high-precision automation in mobile and industrial machinery.

Offerings range from simple proportional valves to servo-proportionals with on-board digital drivers and LVDT transducers for high-precision motion, pressure, and speed control
Subplate and cartridge formats (ISO sizes 06–35, up to 125) support directional, pressure, and flow control applications with configurable electronics (I/O Link and others)
Digital axis cards enable closed-loop axis and P/Q control for position, speed, and force in hydraulic actuators, including explosion-proof variants

A full range of solenoid-operated on-off valves in subplate and screw-in cartridge formats, engineered for low-leak and low-power operation. Options include mechanical, hydraulic, or pneumatic actuation, with ISO sizes up to 32 and flows up to ~700 l/min (350 bar)
Safety valves with inductive spool/poppet position monitoring, cURus certification, and compliance with EU Machinery Directive (2006/42/EC) and PED 2014/68/EU, with capacities to ~6,300 l/min and pressures up to ~420 bar
Modular valves allow configurations of flow, pressure, and directional controls—mountable under ISO solenoid valves typical in industrial builds

Pressure-compensated flow control valves, with or without LVDT transducer and digital drivers, with flows ~45–90 L/min and pressures up to ~210 bar
Pressure control valves: relief, reducing, sequence and compensator valves offered in screw-in, subplate and in-line styles—with or without electronics, typically up to 420 bar
Check valves: leak-free directional designs, direct or pilot operated, in screw-in or in-line formats. Flow ranges up to ~500 L/min, pressure ratings 315–400 bar

Hydraulic cylinders, built to ISO 6020/6022 standards; diameters from 25 to 400 mm, strokes up to 5 meters, pressures up to ~320 bar. Special versions are available for explosive environments, as well as stainless steel options for harsh conditions.
Hydraulic pumps: axial-piston variable displacement (PVPC series) and fixed-displacement vane pumps (PFE series). Designed for high pressure, low noise, long life, and available in ATEX-certified versions for hazardous zones.
Filtration solutions: inline, return-line, and suction filters using high-efficiency microfiber elements to maintain fluid purity and extend component service life.

K3VL / K3VLS : Compact and medium-duty swash plate pumps. Pressure ratings up to ~280 bar (medium) and ~320 bar (high-pressure). M7V / M7X / M3X / K3X Kawasaki’s axial piston motors deliver high-pressure, high-speed performance. The M7V (variable) and M7X (fixed) series offer bent-axis efficiency in a compact swash-plate design. The M3X and K3X provide fixed displacement with superior low-speed stability and reliability for heavy-duty industrial and mobile applications
New K8V Series: A closed-loop pump tailored for hydrostatic transmission in off highway machines, with displacements of 71/90/125 cc and ~400 bar pressure rating. Available in through-drive and tandem versions

HMB Series: Fixed-displacement motors (188–6,800 cc) with low-speed, high torque, hydrostatic balancing, and continuous pressure up to ~250 bar
HMC Series: Variable-displacement motors with two preset options or continuous control (hydro-mechanical or electro-hydraulic). Displacement range: ~492 to 5,326 cc, ~250 bar rating, with freewheel and constant horsepower options
HPC Series: High-pressure, low-speed radial piston motors for marine winches and offshore use. Displacement range ~1,344–6,555 cc, continuous pressure ~250 bar, torque up to 22,440 Nm with dynamic displacement control

Variable-Displacement Axial Piston Pumps: Includes flagship series such as PVG, PVM, PVV, and PVWJ. These deliver high horsepower and pressure (up to ~450 bar / 6,500 psi) with compact design and precise flow control
XD5 Series: Designed for mobile applications, these pumps offer up to 40% higher continuous rated pressure (~5,000 psi), 20% higher flow and speed (up to 2,700 RPM), and quick response, all enabled by their patented Hard-on-Hard wear-resistant technology and hydro-dynamic bearings
Radial-Piston (“D”) Series: Heavy-duty variable delivery pumps known for durability in fixed or reversible configurations. They simplify system design by reducing the need for separate directional or flow-control valves
Key Technologies:Hard-on-Hard rotating components and hydrodynamic bearings—no mechanical wear parts—deliver infinite bearing life, high contamination resistance, versatility in fluid types (water, water-glycol, standard or synthetic oils), and simplified maintenance
