    Hydraulic Cylinders — Carbon Hybrid

    MARK carbon hybrid cylinders are the best of both worlds. Classic, high-strength metal (such as aluminum or steel) combined with lightweight, high-performance carbon fiber (CFRP).

    Advantages at a Glance:

    • Higher efficiency of the cylinder due to:
    • Shorter cycle times
    • Lower mass acceleration and deceleration
    • Fewer CO₂ emissions during operation for better sustainability efforts
    • Higher payload (more load capacity) due to weight savings
    • Preservation of tribological properties meaning less wear on components
    • Less mass, less energy required, lower fuel consumption
    • Corrosion resistant, as carbon is not susceptible to rust or chemicals

    What does carbon hybrid mean?

    Precision-manufactured components such as pistons, rod guides, and cylinder bases are made of aluminum or steel for maximum resilience and durability. The inner tube, or the liner, is made of extremely thin steel (for example, on a micro-cylinder, the liner is only 0.4 mm thick), ensuring optimum tightness and precise sealing clearance.

    The carbon hybrid comes from the fact that all cylinder parts are fully wrapped in carbon fiber. This carbon wrap is the only thing that connects the end pieces, such as the rod guide and cylinder base, and thus means optimal functioning of the cylinder. The carbon fiber is the structural connector, as opposed to welding, gluing or threading.

    Why carbon?

    • High strength: Extremely resistant to tension and compression, ideal for load-bearing structures
    • High rigidity: High modulus of elasticity, advantageous for dynamic loads
    • Low density: Significantly lighter than steel or aluminum, saves weight and energy
    • Corrosion resistance: Rust-free and resistant to many chemicals
    • Good damping behavior: Effectively reduces vibrations and oscillations
    • Fatigue resistance: Stable despite repeated loads, less material fatigue
    • X-ray transparency: Permeable to X-rays, ideal for medical technology & aviation
    • Customizable properties: Fiber orientation & resin matrix can be precisely matched to the application
    • Adjustable thermal expansion: Minimized thermal expansion for precise components

    Where Carbon Hybrid Cylinders make a difference

    Because our carbon fiber cylinders are up to 70% lighter than traditional steel cylinders, using these components reduces energy consumption leading to measurable cost savings over time.

    Below are some areas where our light-weight construction can really make a difference:

    Application

    Where carbon fiber makes a difference

    How it makes a difference

    Lifting platforms

    Load moment

    Reducing weight allows the platform to lift more or lift more safely, because the structure needs to support less self-weight

    Transportation

    Deadweight

    Reducing deadweight increases potential payload capacity, reduces fuel usage, and improves efficiency

    Agricultural technology

    Load moment, corrosion

    Lighter components improve load moments on AG machinery, and because carbon fiber does not corrode, these cylinders are strong in this environment where moisture, dirt, and chemicals are prevalent

    Maritime

    Weight, corrosion

    Lightweight components improve stability and efficiency, while corrosion resistance is critical due to saltwater environments

    Exoskeletons, tools

    Micro-cylinders

    Our small, lightweight micro-cylinders are optimal in wearable exoskeletons or handheld tools, where low weight is essential for ergonomics and mobility

    E-mobility

    Weight reduction

    In electric vehicles, every kilogram saved increases range and efficiency, making lightweight components highly valuable

    Rescue cylinders

    Weight

    Lightweight, powerful cylinders make rescue tools easier to handle for emergency responders, improving speed and safety during operations

    Hydraulic Flow Divider Valve

    When precision is secondary to affordability, flow divider valves can be used. These two-section dividers are designed for compact applications with synchronization errors between ±4 to 5%.

    These divider valves are bidirectional, capable of both dividing and combining flow. The flow division is largely unaffected by the viscosity of the fluid being used or changes in pressure.

    Two models are available, both with identical flow capacity. The difference lies in their housing material and pressure ratings.

    MKA

    2 section divider. Flow Rate: 0.53 to 39 gpm (2 to 150 lpm). Lightweight aluminum body. Peak operating pressure of 3,045 psi (210 bar).

    MKS

    2 section divider. Flow Rate: 0.53 to 39 gpm (2 to 150 lpm). Steel body. Peak operating pressure of 5,075 psi (350 bar).

    Hydraulic Servo Valves – S12 Pro

    Compact Power. Proven Reliability.

    The Domin S12 Pro is the next evolution in high-performance, high-flow hydraulic valves. It builds on the proven reliability of the S6 Pro, which is now used as the first stage for the most advanced two-stage valve in the world.

    The S12 Pro delivers unmatched performance with the same trusted dependability. Combining high flow, excellent dynamics, proven reliability, and low power consumption, the S12 Pro sets a new benchmark in demanding applications.

    With dimensions of 13.25 in (377 mm) in length and 6.9 in (177 mm) in height, the S12 Pro is thoughtfully designed with all components fully enclosed, eliminating exposed wires or sensors. This user-focused design element ensures not only a clean, sleek appearance, but also easier handling and installation.

    This combination of performance and compact design makes the S12 Pro ideal for applications in industrial manufacturing, test simulation, and the energy sector.

    Hydraulic Servo Valves – S6 Pro

    The Domin S6 Pro direct drive servo valve (DDV) has been designed to achieve the best characteristics from two competing valve technologies: fluid amplified EHSVs and DDVs. The S6 Pro has the size, mass, and dynamic capabilities of the most compact EHSV, and the low quiescent leakage and reliability of the best DDV. 

    For applications requiring the results of the S6 Pro X, the S6 Pro model can be upgraded with a mounting plate adapter to achieve the same functionality. 

    Discover Ultimate Power Density

    Experience optimal performance without compromise. Whether in test simulation or industrial manufacturing, the S6 Pro ensures seamless operations and maximum productivity, thanks to its superior design and exceptional power density.

    With the Domin S6 Pro, you get the best of both worlds: the size, mass, dynamic capabilities, and industry-leading power density of the most advanced two-stage valves, paired with low quiescent leakage and unwavering reliability. Experience effortless efficiency, precision and power with the Domin S6 Pro series.

    Available on NG06 port pattern as standard.

    * Conditions outside of the absolute maximum ratings may cause permanent damage to the valve. Operation of the product outside of the nominal operating conditions is not guaranteed and may affect product reliability.

    ** The valve supply must be protected with a 5 AT fuse or equivalent overcurrent protection device.

    *** Valves with a current command signal use a 0.1% tolerance shunt resistor to measure demand current.

    **** The value of the shunt resistor to measure output current should not exceed stated maximum value.

    ***** A current in this range will disable the motor drive until a current outside this range is received at the command input.
