***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics RBACOAN (Material Number: RBACOAN) is a direct-acting pilot relief cartridge designed for use in hydraulic systems to remotely control the pressure setting of other pilot-operated valves. This valve is specifically intended for applications that require load holding, as it efficiently manages pressure settings with its robust design. It features EPDM seals, making it suitable for systems using phosphate ester fluids, while cautioning against exposure to petroleum-based fluids which could damage the seals. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring reliability and longevity. The RBACOAN model is corrosion-resistant and can be configured with external stainless steel components or zinc-nickel plating for enhanced durability in corrosive environments. The valve operates within a maximum pressure of 5000 psi (350 bar) and has a capacity of 0.25 gpm (1 L/min). It offers rapid response times typically around 2 ms, making it ideal for applications requiring quick adjustments. This cartridge valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It allows for adjustable settings through W and Y controls, with options for special settings if required. The valve features a compact design with a hex size of 7/8 inch (22.2 mm) and requires an installation torque between 30 to 35 lbf ft (41 to 47 Nm). This model also comes with an adjustment screw internal hex size of 5/32 inch (4 mm) and a locknut hex size of 9/16 inch (15 mm), with recommended locknut torque ranging from 80 to 90 lbf in (9 to 10 Nm). The RBACOAN weighs approximately .30 lb (.15 kg) and includes a Viton seal kit option under part number 990010006.

Direct-acting, pilot relief cartridges are used to remotely control the pressure setting of other pilot-operated valves. Because capacity is limited to pilot flow, these valves should be used with other higher flow valves.

  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • Main stage orifice is protected by a 150 micron stainless steel screen.
  • Suitable for use in load holding applications.
  • Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
  • W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
  • Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
