Hydraulic Servo Valves – S10 Pro

Unrivaled Performance and Efficiency

Unlock massive energy savings with the Domin S10 Pro series, the most efficient direct drive valve for flows ranging from 13 to 66 gpm (50 to 250 lpm).

Designed to sustain high bandwidth operation at exceptional flows without compromising on operating pressures or duty cycles, the S10 Pro is the pinnacle of reliability and versatility. Where other servo proportional valves struggle with packaging size and weight, the S10 Pro rises above, offering a lighter and more compact alternative to traditional electrohydraulic servo valves.

Experience the difference with the Domin S10 Pro. Whether you’re dealing with high flows or demanding applications, its single-stage design ensures optimal performance every time.

Available on NG10 port pattern as standard. S77 adaptors available.

    Valves can be provided with an enable function. This allows the valve to be enabled or disabled by varying the voltage into the enable pin. Note that valves with code C command type can also be enabled or disabled using the command signal; see the corresponding table for further details.

    * The enable pin is pulled up to Supply + within the valve via 30k. The enable pin may be left floating to enable the valve.

    * 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.

    ** Maximum current draw occurs during chip shear events or operation at high frequencies (e.g. Close to 3dB frequency) and at maximum rated flow. Typical operating conditions require significantly less current.

    *** Current inputs 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.

    * 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 4 AT fuse or equivalent overcurrent protection device.

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

    **** For 4 to 20mA command signal, a current in this range will disable the motor drive until a current outside this range is received at the command input.

    Valves can be provided with an enable function. This allows the valve to be enabled or disabled by varying the voltage into the enable pin. Note that valves with code C command type can also be enabled or disabled using the command signal; see the corresponding table for further details.

    Hydraulic Tool Intensifiers

    What are Tool Intensifiers?

    The tool intensifier utilizes the existing circuit on utility trucks and boosts it to 10,000 psi, allowing you to use large crimping tools without the need for a separate HPU.

    How do Tool Intensifiers work?

    The pressure is intensified with a reciprocating piston that operates at full flow until the crimper bottoms out. Once the tool has bottomed out, the intensifier senses this and starts intensifying the lower pressure flow to 10,000 psi. 

    The tool intensifier plugs directly into your truck’s line. This eliminates the need for an alternate power source, such as batteries that need to be frequently recharged and can be limited to 50 crimps at a time. 

    Tool Intensifier Features:

    The hydraulic intensifier was thoughtfully engineered for the transmission and construction industry.

    Built for continuous, full-day applications: The biggest advantage of the tool intensifier is the way it creates pressure. Due to smart construction of the intensifier design, the device does not build up heat fast and can be used continuously. 

    Precise crimps through simple pressure monitoring: The integrated pressure gauge makes it easy to validate when the 10,000 psi threshold is met, ensuring a perfect crimp. 

    Tool Intensifier Features:

    • Boosts hydraulic tool circuit to 10,000 psi in utility trucks with an inlet pressure as low as 1,850 psi.
    • Can handle back pressures up to 700 psi.
    • Integrated features including a pressure intensifier, single acting control valve, pressure regulator, and a safety relief valve.
    • Built-in pressure gauge to measure crimp head pressure easily.
    • Power large crimping tools without the need for a separate electric or gas engine HPU. 
    • Quieter operation than leading brands.
    • 30% faster than battery-powered HPUs.
    • Fits almost any bucket with adjustable mounting brackets (included).

    Hydraulic Pressure Intensifiers – Single-Stroke Cylinder Type

    The Hänchen intensifier is a custom, heavy-duty, pressure intensifier designed for non-standard applications. This model allows the input fluid to be the same as, or different than, the output fluid as a result of its non-reciprocating, axial type construction. Specifically, the primary cylinder can be run with mineral oil and the secondary chamber can be run with a different fluid such as water or water containing media. This type is commonly found in the hydroforming industry. Additionally, higher flow rates can be achieved in this type of pressure intensifier. These pressure intensifiers can be designed with output pressures of up to 5,000 bar/72,500 psi.

    Hänchen is a supplier and pressure intensifier manufacturer for various applications including construction, mechanical, marine, and industrial.

    The MPL Series includes three models— MPL 1400, MPL 2000, and MPL 4000, all designed for continuous flow in high pressure applications.

    Key Features of the MPL Series:

    • In-line reciprocating pressure intensifiers for uninterrupted flow
    • High pressure and flow applications
    • Optional top plates are available for high pressure connections

    MPL Series Models:

    • High Pressure and Flow (MPL-1400): The MPL 1400 is ideal for high-flow, high-pressure operations. This intensifier has a flow rate up to 13.2 gpm (50 lpm) and output pressure up to 20,300 psi (1,400 bar).
    • Second Highest Pressure (MPL-2000): The MPL 2000 is designed for high-pressure power packs with an output pressure up to 40,600 psi (2,800 bar).
    • Highest Pressure (MPL-4000): The MPL 4000 is perfect for applications requiring maximum pressure performance. This model has the highest pressure in the series with pressure up to 58,000 psi (4,000 bar).

    Technical Data:

    • Inlet Flow:
    • MPL-1400: up to 13.2 gpm (50 lpm)
    • MPL-2000 and MPL-4000: up to 7.9 gpm (30 lpm)
    • Supply pressure: 3,000 psi (200 bar)
    • End pressure rating: The end pressure is dependent on the ratio and is always proportional with the supplied pressure.
    • MPL-1400: 20,300 psi (1,400 bar)
    • MPL-2000: 40,600 psi (2,800 bar)
    • MPL-4000: 58,000 psi (4,000 bar)
    • Multiple intensification ratios
    • All high-pressure valves are integrated
    • Weight: 19.8 lbs (9 kg)
