The Sun Hydraulics RVEALRV (RVEALRV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to the tank port when inlet pressure reaches the set threshold, enabling smooth and quiet throttling of flow to maintain desired pressure levels. It features a vent port for remote control via other pilot or 2-way valves, offering flexibility in various applications. The valve is capable of handling maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such configurations. The main stage orifice is protected by a 150-micron stainless steel screen to ensure durability and reliability. This model is not recommended for load-holding applications due to potential spool leakage. It incorporates Sun Hydraulics' floating style construction to prevent internal binding from excessive installation torque or machining variations. The valve accommodates back pressure on the tank port at a 1:1 ratio with the valve setting and is compatible with EPDM seals for use in systems operating with phosphate ester fluids\u2014though exposure to petroleum-based substances can damage these seals. Key specifications include a capacity of 30 gpm (120 L/min), a maximum operating pressure of 5000 psi (350 bar), and a typical response time of 10 ms. Adjustment involves up to five clockwise turns to increase settings, with torque requirements specified for both installation and locknut adjustments. The RVEALRV model weighs approximately 0.70 lb (0.30 kg) and comes with an optional Viton seal kit (part number: 990202006). This cartridge ensures reliable performance in diverse hydraulic systems where moderate speed and precision are paramount.
