The Sun Hydraulics RVEALPV (RVEALPV) is a ventable, pilot-operated, balanced piston relief cartridge designed to be a normally closed pressure regulating valve. This valve opens to the tank port when the inlet pressure reaches the set threshold, effectively throttling flow to maintain consistent pressure. It features a vent port that facilitates remote control by other pilot or 2-way valves, offering accurate performance with low pressure rise versus flow. The RVEALPV is smooth and quiet in operation and moderately fast in response time, typically around 10 ms. It can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 30 gpm (120 L/min). This cartridge is suitable for cross port relief circuits, but users should consider spool leakage if used in such applications. It incorporates Sun's floating style construction to minimize internal binding due to installation or machining variations. The main stage orifice is protected by a 150-micron stainless steel screen, though it is not recommended for load-holding applications due to potential spool leakage. The back pressure on the tank port directly affects the valve setting at a 1:1 ratio. The RVEALPV comes with EPDM seals for use with phosphate ester fluids; exposure to petroleum-based fluids could damage these seals. Installation requires specific torque settings\u201445-50 lbf ft (61-68 Nm)\u2014and adjustments can be made via an internal hex screw. The model weighs approximately 0.70 lb (0.30 kg), and for maintenance or replacement, Viton seal kits are available under part number 990202006.
