The Sun Hydraulics RSHSKAN (RSHSKAN) is a pilot-operated, balanced poppet sequence valve designed to efficiently manage hydraulic flow in secondary circuits once the inlet port pressure surpasses the set threshold. This valve maintains control over the pressure at port 1 relative to the drain port 3, while remaining unaffected by back pressure at port 2 up to its setting. It can replace two-port relief valves when there's pressure in the return line and is suitable for load holding applications. The RSHSKAN model features interchangeable three-port sequence cartridges that share identical flow paths and cavities for a given frame size. As inlet pressure rises above the valve setting, pilot flow increases proportionally. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and performance. The valve setting can be directly influenced by pressure at port 3 on a one-to-one ratio, with a maximum allowable pressure of 5000 psi (350 bar). Its design incorporates Sun's floating style construction to prevent internal binding due to excessive installation torque or machining variations. The RSHSKAN model accepts maximum pressure at port 2 and is ideal for cross-port relief circuits. It has a capacity of 60 gpm (240 L/min) and operates within a maximum pressure of 5000 psi (350 bar). With typical response times of just 10 milliseconds, this valve ensures quick adjustments with minimal leakage upon reseat. Installation requires specific torques: valve installation torque should be between 150-160 lbf ft (203-217 Nm), while locknut torque ranges from 80-90 lbf in (9-10 Nm). The adjustment mechanism allows for fine-tuning with five turns needed to increase settings. The RSHSKAN model weighs approximately 1.50 lb (0.70 kg) and includes Viton seals as part of its cartridge seal kit options, ensuring reliable performance in various hydraulic systems.
