The Sun Hydraulics RPEEKCV (Material Number: RPEEKCV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed, pressure-limiting valve opens to the tank port when the inlet port pressure reaches the valve setting, effectively throttling flow to control pressure rise. It features low pressure rise versus flow and rapid response times. The cartridge is suitable for cross port relief circuits but not for load holding applications due to spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen. Back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. The RPEEKCV incorporates Sun's floating style construction to minimize internal binding risks from excessive installation torque or machining variations. It fits into Cavity T-10A and belongs to Series 1 with a capacity of 25 gpm (95 L/min). The maximum operating pressure is 5000 psi (350 bar), with typical response times around 2 ms and maximum valve leakage at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Adjustable throughout its range using W or Y controls, it can be set with special settings if specified. Installation requires a torque of 30 \u2013 35 lbf ft (41 \u2013 47 Nm) and uses an adjustment screw with an internal hex size of 5/32 in. (4 mm). The model weighs .30 lb (.15 kg) and includes a Viton seal kit under Cartridge: Viton number 990010006. This relief cartridge offers reliability for systems needing quick response to prevent overpressure situations, ensuring hydraulic system protection with its robust design and precise engineering specifications.
