The Sun Hydraulics RBACWEV (Material Number: RBACWEV) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This valve is intended for use in load-holding applications and is suitable for systems with phosphate ester fluids when configured with EPDM seals. It features a protective 150-micron stainless steel screen for the main stage orifice and incorporates Sun's floating style construction to minimize internal parts binding due to excessive installation torque or machining variations. The valve can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 0.25 gpm (1 L/min). It offers a response time of approximately 2 milliseconds with maximum valve leakage at 110 SUS (24 cSt) being just 5 drops per minute (0.3 cc/min). The RBACWEV model allows adjustment throughout its full range using W or Y controls unless a special setting is specified, which represents the maximum setting of the valve. Additionally, back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio. For corrosive environments, corrosion-resistant versions are available with external stainless steel components or zinc-nickel plated components, identified by model code suffixes AP or LH respectively. The cartridge weighs approximately 0.30 lb (0.15 kg), and its installation requires specific torque settings: valve installation torque between 30-35 lbf\u00b7ft (41-47 Nm), and locknut torque between 80-90 lbf\u00b7in (9-10 Nm). The seal kit for this cartridge uses Viton material, identified by part number 990010006.
