The Sun Hydraulics RVEACVN (RVEACVN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve functions by remaining normally closed until the inlet port 1 pressure reaches the set threshold, at which point it opens to tank port 2 to throttle flow and maintain desired pressure levels. The RVEACVN features a vent port 3 that facilitates remote control via other pilot or two-way valves, offering added versatility. Notably accurate with low pressure rise relative to flow, this valve operates smoothly and quietly with moderate response times. It is capable of handling a maximum operating pressure of 5000 psi (350 bar) and accepts maximum pressure at port 2, making it suitable for cross-port relief circuits\u2014though spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. However, this valve is not recommended for load-holding applications due to potential spool leakage issues. The impact of back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. When equipped with EPDM seals, the RVEACVN is compatible with systems utilizing phosphate ester fluids but should avoid exposure to petroleum-based products as these can damage the seals. Designed with Sun's floating style construction, this cartridge minimizes internal binding risks due to installation torque or machining variations. With a capacity of 30 gpm (120 L/min), factory pressure settings established at 4 gpm (15 L/min), and an installation torque range of 45-50 lbf ft (61-68 Nm), this product ensures reliable performance in demanding environments. The model weighs .70 lb (.30 kg) and includes an adjustment screw internal hex size of 5/32 in (4 mm).
