The Sun Hydraulics RBACCWV (RBACCWV) is a direct-acting, pilot relief cartridge designed to remotely control the pressure settings of other pilot-operated valves. This cartridge is specifically engineered for systems where capacity is limited to pilot flow and should be used in conjunction with higher flow valves. It features EPDM seals, making it suitable for use with phosphate ester fluids, but not with petroleum-based fluids. The main stage orifice is protected by a 150-micron stainless steel screen, enhancing its durability and reliability in load-holding applications. This model incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to installation torque or machining variations. It offers corrosion resistance options denoted by suffixes AP or LH for external stainless steel or zinc-nickel plated components, respectively. The RBACCWV has a cavity size of T-10A and a series 1 capacity of 0.25 gpm (1 L/min), with a maximum operating pressure of 5000 psi (350 bar). The response time is typically 2 ms, and the maximum valve leakage at 110 SUS (24 cSt) is limited to five drops per minute (0.3 cc/min). Adjustments can be made using the W or Y controls unless specified otherwise for special settings. The valve hex size measures 7/8 inch (22.2 mm), with an installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm). For fine adjustments, an internal hex screw size of 5/32 inch (4 mm) and a locknut hex size of 9/16 inch (15 mm) are provided, with recommended locknut torque between 80 and 90 lbf in (9 to 10 Nm). Weighing approximately .30 lb (.15 kg), this cartridge also comes with an optional Viton seal kit 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.
