The Sun Hydraulics RBAEYCN (RBAEYCN) is a two-port, pilot-stage, direct-acting relief cartridge specifically designed as a fully adjustable, normally closed pressure regulating valve. It operates by opening a flow path from port 1 to port 2 when the inlet pressure at port 1 surpasses the spring force setting. This product uses the Sun T-8A two-port cavity, making it an ideal choice for integration with Sun's main stage pilot or vent-to-operate cartridges. Its design eliminates the need for separate pilot lines and requires only one cavity to accommodate both control and primary functions. The valve can handle pressures up to 5000 psi (350 bar) at both ports. The RBAEYCN features a hardened poppet and seat that ensure consistent operation, low leakage rates, and superior wear characteristics. A noteworthy aspect is that backpressure at port 2 is directly additive to the pressure setting at port 1. The cartridge's construction minimizes internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. This cartridge includes EPDM seals suitable for systems with phosphate ester fluids; however, these seals should not be exposed to petroleum-based fluids as they will cause damage. The factory pressure settings are established at flow rates of 2 in\u00b3/min (30 cc/min), with a maximum operating pressure of 5000 psi (350 bar) and response time typically around 2 ms. Maximum valve leakage is specified at 15 drops/min (1 cc/min). Installation parameters include a valve hex size of .78 inches (22.2 mm), installation torque between 20 - 25 lbf-ft (27 - 33 Nm), adjustment screw internal hex size of .532 inches (4 mm), locknut hex size of .916 inches (15 mm), and locknut torque between 80 - 90 lbf-in (9 -10 Nm).

Two-port, pilot-stage, direct-acting relief cartridges are fully adjustable, normally closed pressure regulating valves. When the pressure at port 1 (inlet) is sufficient to overcome the spring force (valve setting), a flow path is opened from port 1 to port 2 (tank).
- Utilizes the Sun T-8A 2-port cavity making it the ideal choice to use in conjunction with Sun's main stage pilot or vent-to-operate cartridges. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function. Note: All 2-position, 2-way pilot stage control cartridges utilize the same cavity and are physically interchangeable. Functionality is the only consideration.
- Note: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
- Ports 1 and 2 may be pressured to 5000 psi (350 bar).
- Hardened poppet and seat provide consistent operation, low leakage rates and superior wear characteristics.
- Backpressure at port 2 (outlet) is directly additive to the pressure setting at port 1 (inlet).
- 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.
- 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.
