The Sun Hydraulics RSJSKBV (RSJSKBV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This valve is particularly useful in applications where it is necessary to regulate pressure in place of 2-port relief valves, especially when there is pressure in the return line. The RSJSKBV model features a 150-micron stainless steel screen protecting the main stage orifice and incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It can handle maximum pressures up to 5000 psi (350 bar) and has a capacity of 120 gpm (480 L/min). The valve's response time is typically around 2 milliseconds, with maximum leakage at reseat being only 10 drops per minute (0.7 cc/min). The adjustment mechanism allows for fine-tuning of the pressure setting with approximately five clockwise turns needed for an increase, utilizing an internal hex size of 5/32 inches (4 mm) for adjustments. Additionally, it features a locknut torque range of 80-90 lbf-in (9-10 Nm) and requires an installation torque between 350-375 lbf-ft (474-508 Nm). Suitable for use in cross-port relief circuits, this sequence valve maintains functionality even under backpressure conditions at port 2, up to its set limit. With its robust design and versatile application potential, the RSJSKBV sequence valve offers reliable performance in demanding hydraulic systems.
