The Sun Hydraulics RPESKNV (RPESKNV) is a pilot-operated, balanced-poppet relief cartridge valve designed for precise pressure regulation. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the preset value, effectively throttling flow to maintain consistent pressure levels. Known for its accuracy, smooth operation, and low noise levels, this valve is ideal for applications requiring stable pressure control without issues like cavitation-induced noise or manifold erosion. It accommodates maximum pressure at port 2 and is suitable for cross-port relief circuits and load-holding applications. The RPESKNV valve is engineered to be relatively insensitive to fluctuations in oil temperature and contamination, featuring a main stage orifice protected by a 150-micron stainless steel screen. Its design incorporates Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. The valve offers an adjustable setting range using W or Y controls, with options for special settings that define the maximum adjustment limit. This model fits into a T-10A cavity and has a capacity of up to 25 gpm (95 L/min), with factory pressure settings established at 4 gpm (15 L/min). It can operate under pressures up to 5000 psi (350 bar) with a typical response time of 7 ms. The maximum valve leakage at 110 SUS (24 cSt) is minimal at only 10 drops/min (0.7 cc/min). Installation specifications include a valve hex size of 7/8 inch (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). The adjustment screw and locknut have specific hex sizes and torque requirements for secure setup. Weighing just .30 lb (.15 kg), it comes with an optional Viton seal kit for enhanced durability in various fluid conditions.
