The Sun Hydraulics RPESYNV (Material Number: RPESYNV) is a pilot-operated, balanced poppet relief cartridge valve designed for precise pressure regulation. This normally closed valve opens to the tank port when the inlet pressure reaches the set threshold, effectively throttling flow to maintain desired pressure levels. Known for its accuracy and smooth operation, the RPESYNV is engineered to minimize issues related to cavitation, such as noise and manifold erosion. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits and load-holding applications. The valve's design includes a main stage orifice protected by a 150-micron stainless steel screen and is resilient against variations in oil temperature and contamination. The RPESYNV features Sun's floating style construction, which reduces the risk of internal binding due to installation torque or machining variations. It accommodates back pressure on the tank port at a 1:1 ratio with the valve setting. This model allows adjustments through W or Y controls across its full range unless a special setting is specified, which then becomes its maximum setting. With a capacity of 25 gpm (95 L/min) and a maximum operating pressure of 5000 psi (350 bar), it responds swiftly with an approximate response time of 7 ms. The valve has minimal leakage rates at standard conditions and comes with specific installation requirements: a hex size of 7/8 inch (22.2 mm) and an installation torque between 30-35 lbf ft (41-47 Nm). The adjustment screw features an internal hex size of 5/32 inch (4 mm), while the locknut requires torque between 80-90 lbf in (9-10 Nm). Weighing approximately .30 lb (.15 kg), this cartridge valve incorporates Viton seals for reliable performance across various applications.
