The Sun Hydraulics RVESCCV (RVESCCV) is a ventable, pilot-operated, balanced poppet relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve begins to open when the inlet port pressure reaches the preset level, diverting flow to the tank port to maintain desired pressure levels. It features a vent port that allows for remote control by other pilot or 2-way valves. The RVESCCV is known for its accuracy, low pressure rise versus flow, smooth operation, and moderate response time of approximately 2 ms. It effectively minimizes issues related to cavitation such as noise and manifold erosion due to its internal modulating mechanism. This cartridge is ideal for load-holding applications, provided any valving on the vent port is zero-leak. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits. The valve's design ensures it remains relatively insensitive to variations in oil temperature and contamination. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and backpressure at the tank port directly influences the valve setting at a 1:1 ratio. The RVESCCV incorporates Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations in cavities/cartridges. It fits into cavity T-2A Series 2 with a capacity of 25 gpm (95 L/min) and operates at pressures up to 5000 psi (350 bar). The valve's adjustment requires about 5-5 turns clockwise to increase settings, with specific torque requirements detailed for installation and adjustment components. Weighing approximately 1.60 lb (0.70 kg), this model comes with a Viton seal kit option (990402006) for enhanced durability in various environments.
