SUN Overflow Valve RBAE-LAN With Hardened Poppet And Seat For Consistent Operation

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.

• Hardened poppet and seat provide consistent operation, low leakage rates and superior wear characteristics
• Ports 1 and 2 may be pressured to 5000 psi (350 bar)
• Backpressure at port 2 (outlet) is directly additive to the pressure setting at port 1 (inlet)
• Incorporates the Sun floating style construction to minimize internal parts binding
• EPDM seals for use in systems with phosphate ester fluids (not compatible with petroleum-based fluids)

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.
