The Sun Hydraulics RVEACIN (RVEACIN) is a ventable, pilot-operated, balanced piston relief cartridge designed to serve as a normally closed pressure regulating valve. When the inlet port 1 reaches the predetermined valve setting, it opens to the tank port 2, allowing throttling flow to regulate pressure effectively. This model features a vent port 3 for remote control through other pilot or two-way valves. Known for its accuracy and smooth operation, the RVEACIN offers low pressure rise versus flow and moderate speed. Notably, it can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. It's important to note that this valve is not ideal for load-holding applications due to spool leakage. The RVEACIN incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. Cartridges with EPDM seals are compatible with phosphate ester fluids but are vulnerable to petroleum-based substances. With a cavity of T-2A Series 2 and a capacity of 30 gpm (120 L/min), the factory pressure settings are established at 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar) with control pilot flow ranging from 10-15 in\u00b3/min (0.16-0.25 L/min). Typical response time is around 10 ms, while maximum valve leakage at specific conditions is noted as 3 in\u00b3/min (50 cc/min). The valve has an adjustment range involving five clockwise turns for setting increase and requires specific torques for installation and locknut adjustments.
