The Sun Hydraulics RVEAKPV (RVEAKPV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to the tank port when inlet port pressure reaches the set value, effectively throttling flow to maintain desired pressure levels. Notably, it features a vent port that allows remote control via other pilot or 2-way valves, enhancing its versatility. The valve excels in applications requiring accuracy and low pressure rise versus flow, delivering smooth and quiet performance with moderate speed. The RVEAKPV can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, although users should consider spool leakage in such applications. It is not recommended for load-holding applications due to potential spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. 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 are vulnerable to damage from petroleum-based substances. The valve incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. Key specifications include a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), and control pilot flow ranging from 10-15 in\u00b3/min (0.16-0.25 L/min). Typical response time is around 10 ms, with maximum valve leakage at specified conditions being 3 in\u00b3/min (50 cc/min). The adjustment mechanism involves up to five clockwise turns to increase settings, with specific dimensions provided for installation tools and torques. The model weighs approximately 0.70 lb (0.30 kg) and comes with a Viton seal kit option for enhanced sealing performance.
