The Sun Hydraulics RSJSCCV (RSJSCCV) is a pilot-operated, balanced poppet sequence valve designed to manage the flow to a secondary circuit once the pressure at inlet port 1 surpasses the valve setting. This sequence valve precisely controls pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to the preset valve threshold. It can replace two-port relief valves in scenarios where return line pressure exists, offering versatility in hydraulic systems. The RSJSCCV features interchangeable three-port sequence cartridges with consistent flow paths and cavity sizes, facilitating easy integration into existing setups. Its main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability under high-pressure conditions. With a maximum operating pressure of 5000 psi (350 bar), this valve provides robust performance for demanding applications. The modulating action occurs within the cartridge itself, making it resistant to cavitation-related issues such as noise and manifold erosion. Additionally, it supports maximum pressure at port 2 and is suitable for cross-port relief circuits. The Sun floating style construction minimizes internal part binding due to excessive installation torque or machining variations. The RSJSCCV has a capacity of 120 gpm (480 L/min) and factory pressure settings established at 4 gpm (15 L/min). It offers a control pilot flow of 15-20 in\u00b3/min (0.25-0.33 L/min) with a typical response time of just 2 ms. The valve's leakage rate upon reseat is minimal at only ten drops per minute (0.7 cc/min). Installation requires specific torque settings for both the valve body and locknut, ensuring secure placement in hydraulic systems. This model weighs approximately 3.10 lb (1.40 kg) and utilizes Viton seals for reliable performance across various applications.
