The Sun Hydraulics RSJCLEN (RSJCLEN) is a pilot-operated, balanced piston sequence valve designed to manage flow in secondary circuits after the pressure at inlet port 1 surpasses the valve's preset level. It is capable of controlling the pressure at port 1 relative to the drain port 3, with an insensitivity to back pressure at port 2 up to the valve setting. This makes it suitable for applications where pressure regulation is required instead of using two-port relief valves, especially when there's pressure in the return line. The valve features a main stage orifice protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction, minimizing internal part binding due to installation torque or machining variations. The RSJCLEN model has a maximum operating pressure of 5000 psi (350 bar) and can handle a flow capacity of up to 120 gpm (480 L/min). It exhibits a typical response time of 10 milliseconds and has maximum leakage of 5 in\u00b3/min (80 cc/min) at 110 SUS (24 cSt) and 1000 psi (70 bar). The adjustment can be made using an internal hex screw with five full clockwise turns increasing the setting, while control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min). The valve is not suitable for load holding applications due to spool leakage. Installation requires a torque between 350 and 375 lbf ft (474 and 508 Nm), with specific hex sizes for adjustment screw and locknut being \\( \\frac{5}{32} \\) in. (4 mm) and \\( \\frac{9}{16} \\) in. (15 mm), respectively. The model weighs approximately 3.10 lb (1.40 kg), and it uses Viton seals as part of its cartridge seal kit configuration.
