The Sun Hydraulics RVEALAE (RVEALAE) is a ventable, pilot-operated, balanced piston relief cartridge designed to regulate pressure efficiently. This normally closed pressure-regulating valve begins to open to the tank port when the inlet port pressure reaches the valve setting, throttling flow to maintain desired pressure levels. It features a vent port that allows remote control via other pilot or 2-way valves, offering precision and low-pressure rise against flow. The valve is smooth, quiet, and moderately fast in operation. Notably, it can accept maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should be aware of potential spool leakage in such applications. The main stage orifice is protected by a robust 150-micron stainless steel screen. This model is not ideal for load-holding applications due to possible spool leakage. Any backpressure on the tank port directly adds to the valve setting at a 1:1 ratio. The cartridge's EPDM seals are specifically intended for systems utilizing phosphate ester fluids and may be damaged by petroleum-based substances. The Sun floating style construction minimizes internal part binding due to installation torque or machining variations. Key specifications include a cavity T-2A series with a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), and control pilot flow between 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 approximately 3 in\u00b3/min (50 cc/min). Adjustment involves up to five clockwise turns, with specific torque requirements for installation and locknut adjustments ensuring secure setup and operation stability.
