SH7V Series

Product catalog summary
Description and Features: The SH7V series motors are variable displacement axial-piston motors designed for both open and closed circuits. They are built with high-quality materials, allowing continuous operation up to 430 bar and peak performance at 480 bar. These motors are durable, efficient, and can handle high axial and radial loads, making them suitable for mobile and industrial applications.
Technical Specifications: The motors use FKM seals with a maximum case drain pressure of 10 bar. Operating pressures are 430 bar continuous and 480 bar peak, with a total pressure limit of 700 bar for series-connected motors. Proper filtration is crucial, with a contamination class of 21/19/16 according to ISO 4406:1999. Operating temperatures range from -25ºC to 115ºC, and suitable fluids are mineral-based with specific additives, with viscosity between 15-40 cSt.
Installation and Operation: SH7V motors can be installed in any position but must be drained. Vertical shaft installation above the tank has limitations. They can be equipped with a flushing valve for closed circuit use, and the port plates have both lateral and frontal ports, with unused ports plugged.
Technical Data: Available in sizes 055, 075, 108, and 160, these motors offer high torque and power outputs, with specific speed and torque constants. The maximum permissible speed varies with displacement, and peak operations should not exceed 1% of each minute.
Model Code: The SH7V model code identifies configuration options, including series, displacement, mount flange, shaft end, ports, and control types. It is essential to specify all alphanumeric digits when ordering.
Regulator Types and Features: Various pressure regulators and control systems are detailed, including RPI, ROI, RED, and RID, each offering different pressure control features and settings.
Pressure Settings: Pressure settings range from 100 to 400 bar for various regulators, with adjustments possible through external pilot pressures.
Voltage and Control Options: Regulators are available in different voltage configurations, including 12V and 24V, with options for Deutsch connectors and varying control orifice sizes.
Displacement Settings: Regulators allow for adjustments from maximum to minimum displacement, with standard and custom configurations available.
Flushing Valve Features: Flushing valves are available with different flow rates and orifice diameters for system flushing requirements.
Additional Options: Various painting options and tachometer configurations are available for customization.
Important Considerations: Pressure settings are valid only under maximum and minimum displacement conditions. Consultation with control diagrams or the technical department may be necessary for specific settings and configurations.
Specifications and Ordering Information: It is crucial to specify the control pressure setting when ordering. The document outlines the relationship between the direction of rotation of the SH7V motor shaft and the direction of flow.
Control Types and Pressure Settings: Various control types are detailed, including ROE, ROI, 2IN, 2IE, 2EN, 2EE, RIN, and RIE, each with specific pressure and displacement control features.
General Notes: Reliable operation requires an operating pressure of at least 20 bar at port A (B). If not guaranteed, an auxiliary pressure of 20 bar should be applied at port Y1.
Technical Specifications: The document outlines various regulators and their control mechanisms, specifying piloting ports and mounting dimensions for SH7V motors.
Flushing Valve: A built-in flushing valve is available for closed circuit operations, specifically for SH7V 160 with two-position controls.
Tachometer Version: Specifications for tachometer versions of SH7V motors are provided, including dimensions and output signal characteristics.
Legal and Usage Notes: Brevini Fluid Power S.p.A. reserves the right to make changes to technical features without prior notice. Compliance with operating limits is emphasized for safety, and technical features are non-binding.
