The Sun Hydraulics RBAAOCN (RBAAOCN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. It is optimized for applications where capacity is limited to pilot flow and should be paired with higher flow valves for optimal performance. The valve features a main stage orifice protected by a 150-micron stainless steel screen, making it suitable for load holding applications. The back pressure on the tank port (port 2) directly adds to the valve setting at a 1:1 ratio. This model can be configured with EPDM seals specifically for systems using phosphate ester fluids; exposure to petroleum-based fluids will compromise these seals. With corrosion-resistant options available, the cartridges can be used in corrosive environments and are identifiable by model code suffixes AP or LH for external stainless steel or zinc-nickel plated components, respectively. The RBAAOCN incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. It fits a Cavity T-3A Series 2 and has a capacity of 0.5 gpm (2 L/min) with a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 2 ms, with maximum valve leakage at 110 SUS being five drops per minute (0.3 cc/min). Adjustment settings are made through clockwise turns, with up to five turns available for increasing settings. Installation requires specific torque values: valve installation torque is between 45-50 lbf ft (61-68 Nm), while the locknut torque ranges from 80-90 lbf in (9-10 Nm). This model weighs approximately 0.50 lb (0.25 kg) and uses Viton seal kit number 990203006.

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.
- 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.
- 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.
- 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.
