The Sun Hydraulics RVEALMV (Material Number: RVEALMV) is a ventable, pilot-operated, balanced piston relief cartridge valve designed for precise pressure regulation in hydraulic systems. This normally closed pressure regulating valve opens to the tank port when the inlet port reaches the set pressure, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control via other pilot or 2-way valves, enhancing its versatility and control precision. This valve is characterized by its accuracy, low-pressure rise versus flow, smooth operation, quiet performance, and moderate speed. The RVEALMV can accept maximum pressure at port 2 and is suitable for use in cross-port relief circuits, although spool leakage should be considered in such applications. Its main stage orifice is safeguarded by a 150-micron stainless steel screen. However, it is not suitable for load-holding applications due to potential spool leakage. The back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. This cartridge valve incorporates Sun's floating style construction to minimize internal part binding caused by excessive installation torque or machining variations. It can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 30 gpm (120 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with control pilot flow ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). The response time is typically around 10 ms with maximum valve leakage at specified conditions being 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar). For systems using phosphate ester fluids, cartridges with EPDM seals are recommended as exposure to petroleum-based fluids will damage these seals. The RVEALMV model weighs approximately .70 lb (.30 kg) and includes detailed specifications for installation torque and adjustment settings.
