The Sun Hydraulics RVGSLBN (RVGSLBN) is a ventable, pilot-operated, balanced poppet relief cartridge designed for pressure regulation in hydraulic systems. It is a normally closed valve that opens to the tank port when the inlet pressure reaches the set level, allowing flow to throttle and maintain regulated pressure. This model features a vent port that enables remote control through other pilot or 2-way valves. Notably, it offers accurate performance with low pressure rise versus flow, smooth operation, and moderate response speed while being immune to cavitation-related issues such as noise and manifold erosion. The RVGSLBN is suitable for load-holding applications, provided any valving on the vent port is zero leak. It can handle maximum pressure at port 2 and is appropriate for cross-port relief circuits. A remote pilot relief on the vent port can control the valve below its own setting, making it versatile in various applications. The valve's performance remains stable despite varying oil temperatures and contamination levels due to its robust design. Key specifications include a maximum operating pressure of 5000 psi (350 bar), capacity of 50 gpm (200 L/min), and typical response time of 2 ms. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability in demanding environments. The valve incorporates Sun's floating style construction to minimize internal binding from installation torque or machining variations. For systems utilizing phosphate ester fluids, EPDM seals are available; however, exposure to petroleum-based substances should be avoided as it may damage these seals. The RVGSLBN also features adjustable settings with five clockwise turns required to increase the setting. It includes Viton seal kits for maintenance and weighs approximately 1.60 lb (0.70 kg).
