The Sun Hydraulics RVESLCN (RVESLCN) is a ventable, pilot-operated, balanced poppet relief cartridge designed to function as a normally closed pressure regulating valve. It activates when the inlet port 1 pressure reaches the pre-set level, opening to the tank port 2 and throttling flow to manage pressure efficiently. This model features a vent port 3 for remote control by other pilot or two-way valves, ensuring precise operation with low pressure rise versus flow characteristics. The valve is engineered for smooth and quiet operation with moderate speed and is immune to cavitation-related issues such as noise and manifold erosion due to its internal modulating capabilities. The RVESLCN is suitable for load-holding applications, provided that any valving on the vent port 3 is zero leak. It can handle maximum pressure at port 2, making it ideal for cross-port relief circuits. A remote pilot relief on port 3 will allow control below its own setting. The valve's performance remains stable across varying oil temperatures and contamination levels due to its robust construction, including a main stage orifice protected by a 150-micron stainless steel screen. The design incorporates Sun's floating style construction, minimizing risks of internal part binding from excessive installation torque or machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), a capacity of 25 gpm (95 L/min), and typical response time of 2 ms. The RVESLCN also features an adjustment capability with five clockwise turns to increase settings, ensuring flexibility in various applications. This model comes equipped with Viton seal kits for enhanced durability and reliability in demanding environments.
