The Sun Hydraulics RVCAQEN (RVCAQEN) 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 threshold, allowing for controlled flow and pressure management. It features a vent port for remote control via other pilot or 2-way valves, making it adaptable for diverse applications. The RVCAQEN is known for its accuracy, low-pressure rise versus flow, smooth operation, quiet performance, and moderate 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 setups. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. While not suitable for load-holding applications due to potential spool leakage, this valve accommodates back pressure on the tank port at a 1:1 ratio with the valve setting. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended; these seals are vulnerable to damage from petroleum-based substances. Incorporating Sun's floating style construction minimizes risks of internal binding caused by excessive installation torque or machining variations. The RVCAQEN operates within a cavity T-11A series 1 capacity of up to 15 gpm (60 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with typical response times around 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is approximately 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The adjustment mechanism allows for fine-tuning with up to five turns clockwise to increase settings and requires specific torque settings during installation and adjustment processes.
