RBAE
Direct-acting relief valve - pilot capacity
SERIES P / CAPACITY: 10 L/min. / CAVITY: T-8A
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).
TECHNICAL DATA
Factory Pressure Settings Established at 30 cc/min.
Maximum Operating Pressure 350 bar
Response Time - Typical 2 ms
Maximum Valve Leakage at 110 SUS (24 cSt) 1 cc/min.
Locknut Hex Size 15 mm
Locknut Torque 9 - 10 Nm

TECHNICAL FEATURES
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.
