The Sun Hydraulics RVEAMDN (RVEAMDN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve begins to open to tank port 2 when the inlet pressure at port 1 reaches the preset threshold, effectively throttling flow to maintain desired pressure levels. Featuring a vent port 3, the RVEAMDN allows for remote control via other pilot or two-way valves, enhancing its versatility in various applications. Its design ensures accuracy with low pressure rise versus flow and delivers smooth, quiet operation with moderate speed. This cartridge is particularly suitable for cross-port relief circuits due to its ability to accept maximum pressure at port 2. However, users should be mindful of spool leakage when implementing it in such settings and avoid using it in load-holding applications. The main stage orifice is safeguarded by a robust 150-micron stainless steel screen, ensuring durability and reliability under demanding conditions. Backpressure on tank port 2 directly influences the valve setting at a 1:1 ratio, providing predictable performance adjustments. When equipped with EPDM seals, this model is compatible with systems utilizing phosphate ester fluids but should not be exposed to petroleum-based substances which can damage the seals. The Sun floating style construction minimizes potential internal binding issues due to excessive installation torque or machining variations. With a capacity of up to 30 gpm (120 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve offers reliable performance in high-pressure environments. It features an adjustment range that requires approximately five full clockwise turns to increase settings and includes user-friendly installation specifications such as a hex size of 1-1/8 inches (28.6 mm) and an installation torque range of 45-50 lbf ft (61-68 Nm).
