The Sun Hydraulics RSJSKQV (RSJSKQV) 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 sequence valve controls pressure at port 1 relative to the pressure at drain port 3 and is insensitive to back pressure at port 2 up to the valve setting. It can regulate pressure in place of two-port relief valves if there is pressure in the return line. All three-port sequence cartridges are interchangeable, featuring the same flow path and cavity for a given frame size. The valve's pilot flow increases as the inlet pressure rises above the valve setting relative to the drain pressure. It includes a main stage orifice protected by a 150-micron stainless steel screen and can handle pressures up to 5000 psi (350 bar) at port 3, which adds directly to the valve setting at a 1:1 ratio. The design ensures immunity to cavitation-related issues such as noise and manifold erosion due to internal modulating within the cartridge. The RSJSKQV accepts maximum pressure at port 2, making it suitable for cross-port relief circuits, and incorporates Sun's floating style construction to prevent internal part binding from excessive installation torque or machining variations. It fits into cavity T-19A, Series 4 with a capacity of up to 120 gpm (480 L/min), operating under maximum pressures of 5000 psi (350 bar). The control pilot flow ranges between 15 - 20 in\u00b3/min (0.25 - 0.33 L/min) with a typical response time of approximately two milliseconds. Maximum valve leakage upon reseat is limited to ten drops per minute (0.7 cc/min). Adjustment features include five full clockwise turns for increased settings, with specific torque requirements for installation and locknut adjustments.
