The Sun Hydraulics RVEAMBV (RVEAMBV) is a ventable, pilot-operated, balanced piston relief cartridge designed as a normally closed pressure regulating valve. This model opens to the tank port when the inlet port pressure reaches the valve setting, effectively throttling flow to manage pressure. It features a vent port that allows for remote control via other pilot or 2-way valves, making it versatile for various applications. Notably accurate and smooth in operation, these valves exhibit low pressure rise relative to flow and are known for their quiet performance and moderate response speed. The RVEAMBV can accept maximum pressure at port 2 and is suitable for cross-port relief circuits, although spool leakage should be considered in such configurations. The main stage orifice is safeguarded by a 150-micron stainless steel screen. However, due to spool leakage, this cartridge is not recommended for load-holding applications. Additionally, back pressure on the tank port directly affects the valve setting at a 1:1 ratio. This model incorporates Sun's floating style construction to prevent internal parts from binding due to excessive installation torque or machining variations. Cartridges with EPDM seals are compatible with systems using phosphate ester fluids but should not be exposed to petroleum-based substances as they may damage the seals. Key specifications include a cavity type of T-2A Series 2 with a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), and control pilot flow ranging from 10-15 in\u00b3/min (0.16-0.25 L/min). The typical response time is around 10 ms, with maximum valve leakage at specified conditions being about 3 in\u00b3/min (50 cc/min). The adjustment screw requires an internal hex size of 5/32 inches (4 mm), while installation torque ranges between 45-50 lbf\u00b7ft (61-68 Nm). The model weight is approximately .70 lb (.30 kg).
