The Sun Hydraulics RVEALEN (Material Number: RVEALEN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the set level, effectively throttling flow to maintain desired pressure levels. It features a vent port for remote control, allowing integration with other pilot or two-way valves. The valve is known for its accuracy, smooth operation, and moderate response speed. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. This cartridge is not recommended 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. Cartridges with EPDM seals are compatible with phosphate ester fluids but can be damaged by petroleum-based substances. The Sun floating style construction reduces the likelihood of internal part binding from installation torque or machining variations. The RVEALEN operates within a cavity T-2A Series 2 and has a capacity of 30 gpm (120 L/min). Its maximum operating pressure is 5000 psi (350 bar), with control pilot flow ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min) and typical response time of about 10 ms. Maximum valve leakage at specified conditions is limited to 3 in\u00b3/min (50 cc/min). Adjustments are made via an internal hex screw requiring specific torque settings for secure installation and operation stability.
