The Sun Hydraulics RSHSKAV (RSHSKAV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This model controls pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. It can regulate pressure in lieu of two-port relief valves when there is return line pressure. All three-port sequence cartridges are interchangeable, offering consistent flow paths and cavity compatibility for a given frame size. The valve's main stage orifice is protected by a 150-micron stainless steel screen, and it adds pressure at port 3 directly to the valve setting at a 1:1 ratio, with a maximum limit of 5000 psi (350 bar). Ideal for load-holding applications, these valves are designed to mitigate issues like cavitation-related noise and erosion due to their internal modulation. They can handle maximum pressure at port 2, making them suitable for cross-port relief circuits. The Sun floating style construction reduces risks of internal binding from excessive torque or machining variations. With a cavity type T-17A Series 3 and a capacity of up to 60 gpm (240 L/min), this valve operates under pressures up to 5000 psi (350 bar), with typical response times of about 10 ms and minimal leakage upon reseat. Adjustments require five clockwise turns to increase settings, and installation demands specific torque values for both the valve body and adjustment components. The model weighs approximately 1.50 lb (0.70 kg) and includes Viton seal kits for enhanced performance reliability.
