The Sun Hydraulics RVISKCN (Material Number: RVISKCN) is a ventable, pilot-operated, balanced poppet relief cartridge designed to function as a normally closed pressure regulating valve. This product is engineered to open at the inlet port when the pressure reaches the pre-set level, allowing flow to tank port 2 to regulate pressure effectively. It features a vent port (port 3) for remote control by other pilot or two-way valves, ensuring accurate and smooth operations with low noise and minimal pressure rise. The internal modulating mechanism makes it resistant to cavitation-related issues such as noise and manifold erosion. This relief cartridge is suitable for load-holding applications, provided that any valving on the vent port is zero-leak. It can handle maximum pressure at port 2, making it apt for cross-port relief circuits. A remote pilot relief on the vent will enable control below its own setting. The valve's performance remains stable despite variations in oil temperature or contamination levels due to its robust design. It includes a main stage orifice protected by a 150-micron stainless steel screen. The Sun Hydraulics RVISKCN incorporates floating style construction, minimizing risks of internal binding due to excessive torque or machining variations. It fits Cavity T-19A and offers a capacity of up to 120 gpm (480 L/min) with a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 15-20 in\u00b3/min (0.25-0.33 L/min), with typical response times around 2 ms and maximum valve leakage at reseat being 10 drops/min (0.7 cc/min). The adjustment requires approximately five clockwise turns to increase settings, with specific installation and locknut torque specifications provided for secure setup.
