The Sun Hydraulics RSFEABV (RSFEABV) is an air-controlled, pilot-operated, balanced piston sequence valve designed for precise pressure regulation in hydraulic systems. This valve utilizes compressed air over a diaphragm to control the pressure setting instead of an adjustable spring, making it highly adaptable for applications requiring explosion-proof remote control. The RSFEABV model is engineered to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting, while being insensitive to back pressure at port 2 up to the valve's setting. The valve's design incorporates Sun's floating style construction, minimizing potential internal binding issues due to excessive installation torque or machining variations. Functionally interchangeable across all 3-port sequence cartridges of the same frame size, this model features a cavity T-2A series with a capacity of 30 gpm (120 L/min) and a pilot ratio of 20:1 hydraulic to air. The maximum operating pressure is rated at 2000 psi (140 bar), with response times typically around 10 ms. For optimal performance, the maximum air pilot pressure should not exceed 150 psi (10.5 bar), and the pressure at port 3 drain should remain under 1000 psi (70 bar). The RSFEABV supports factory pressure settings established at 4 gpm (15 L/min) and ensures minimal leakage with specifications set at a maximum of 3 in\u00b3/min (50 cc/min) at viscosity levels of 110 SUS (24 cSt). This robust valve weighs approximately .60 lb (.30 kg) and requires an installation torque between 45 - 50 lbf ft (61 - 68 Nm). It is compatible with Viton seal kits for enhanced durability and performance under various operating conditions.
