The Sun Hydraulics RBACQDN (RBACQDN) is a direct-acting pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This model is ideal for applications where capacity is limited to pilot flow and should be used in conjunction with higher flow valves. The RBACQDN is configured with EPDM seals, making it suitable for use in systems with phosphate ester fluids, but it should not be exposed to petroleum-based fluids, greases, or lubricants as these can damage the seals. The main stage orifice of this cartridge is protected by a 150-micron stainless steel screen, enhancing its reliability in load-holding applications. It features a back pressure on the tank port that is directly additive to the valve setting at a 1:1 ratio. The valve offers adjustable settings through W and Y controls, which can be specified with or without a special setting; when unspecified, adjustments can be made throughout its full range. The corrosion-resistant design is intended for use in harsh environments and can be identified by model code suffixes AP or LH for external stainless steel or zinc-nickel plated components, respectively. The RBACQDN incorporates Sun's floating style construction to minimize internal parts binding due to excessive installation torque or machining variations. This Series 1 cartridge has a cavity T-10A and offers a capacity of 0.25 gpm (1 L/min) with a maximum operating pressure of 5000 psi (350 bar). Its response time is typically 2 milliseconds with maximum valve leakage at 110 SUS (24 cSt) being 5 drops/min (0.3 cc/min). Installation specifics include a valve hex size of 7/8 inch (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm).

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.
