The Sun Hydraulics RSJCKDV (RSJCKDV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. It controls the pressure at port 1 relative to the drain port 3 and remains unaffected by back pressure at port 2 up to the valve setting. This model can regulate pressure in place of two-port relief valves if there's pressure in the return line, making it versatile for various hydraulic applications. All three-port sequence cartridges from Sun Hydraulics are interchangeable, maintaining the same flow path and cavity for a given frame size. As inlet pressure at port 1 rises above the valve setting, pilot flow increases accordingly. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and pressure at port 3 directly adds to the valve setting at a 1:1 ratio, not exceeding 5000 psi (350 bar). However, it is unsuitable for load-holding applications due to spool leakage. The RSJCKDV features Sun's floating style construction to reduce internal part binding risks from excessive installation torque or machining variations. It fits cavity T-19A Series 4 with a capacity of up to 120 gpm (480 L/min) and operates under a maximum pressure of 5000 psi (350 bar). Control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with a typical response time of about 10 ms. Maximum valve leakage is rated at five in\u00b3/min (80 cc/min) under specific conditions. The adjustable setting can be increased by turning clockwise up to five turns, and various control options are available with or without special settings. The model weighs approximately 3.10 lb (1.40 kg) and requires specific torques for installation and adjustments, ensuring reliability and performance across diverse hydraulic systems.
