The Sun Hydraulics RPESLNV (RPESLNV) is a pilot-operated, balanced poppet relief cartridge designed for efficient pressure regulation. These normally closed valves open to the tank port when inlet pressure reaches the set level, effectively throttling flow to maintain desired pressure. Known for their accuracy, smooth operation, and quick response time of approximately 7 ms, these valves offer low pressure rise versus flow characteristics. They are engineered to withstand maximum pressures up to 5000 psi (350 bar) and are suitable for use in cross port relief circuits and load holding applications. The valve's main stage orifice is protected by a 150-micron stainless steel screen, enhancing durability against oil contamination and temperature variations. The RPESLNV model is equipped with Sun's floating style construction, minimizing the risk of internal parts binding due to installation torque or machining variations. Back pressure on the tank port directly affects valve settings at a 1:1 ratio, providing precise control in various hydraulic systems. With an adjustable range facilitated by W or Y controls, this valve can be fine-tuned throughout its entire range unless a special setting is specified. Installation specifications include a cavity T-10A series with a capacity of 25 gpm (95 L/min), requiring an installation torque of 30-35 lbf ft (41-47 Nm). The valve features an adjustment screw with an internal hex size of 5/32 in (4 mm) and locknut hex size of 9/16 in (15 mm), ensuring secure adjustments with locknut torque between 80-90 lbf in (9-10 Nm). The RPESLNV weighs .30 lb (.15 kg) and utilizes Viton seals for reliable performance across diverse applications.
