The Sun Hydraulics RVEAKUV (RVEAKUV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. These normally closed valves open to tank port 2 when the inlet port 1 pressure reaches the valve setting, effectively throttling flow to maintain desired pressure levels. The RVEAKUV model features a vent port 3 that facilitates remote control via other pilot or two-way valves, offering enhanced adaptability and control. Notably accurate with low pressure rise versus flow, these valves are characterized by their smooth operation and moderate response speed. The valve's design allows it to accept maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. Its main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability even under challenging conditions. It's important to note that this valve is not recommended for load-holding applications due to potential spool leakage, and back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available; caution should be taken as exposure to petroleum-based fluids can damage these seals. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of 30 gpm (120 L/min) and a maximum operating pressure of 5000 psi (350 bar), this cartridge offers robust performance for demanding applications. Additional specifications include an adjustment range facilitated by five clockwise turns and installation torque requirements of 45-50 lbf ft (61-68 Nm).
