The Sun Hydraulics RVEAMQV (RVEAMQV) is a ventable, pilot-operated, balanced piston relief cartridge designed to regulate pressure effectively in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the set level, allowing for precise pressure control. It features a vent port that facilitates remote control through other pilot or 2-way valves. Known for its accuracy and smooth operation, this valve exhibits low pressure rise relative to flow and is moderately fast in response. The RVEAMQV model can handle maximum pressures at port 2 and is suitable for cross-port relief circuits, although spool leakage should be considered in such applications. It incorporates a 150-micron stainless steel screen protecting the main stage orifice and uses Sun's floating style construction to prevent internal binding due to installation torque or machining variations. This cartridge is not recommended for load holding applications due to potential spool leakage. Back pressure on the tank port affects the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available; however, these seals are incompatible with petroleum-based fluids. The valve has a capacity of 30 gpm (120 L/min) and can operate at pressures up to 5000 psi (350 bar). Its design includes an adjustment mechanism allowing for setting changes via clockwise turns, with specific torque requirements for installation and locknut adjustments. The RVEAMQV model weighs approximately 0.70 lb (0.30 kg) and offers reliable performance across various hydraulic applications where precise pressure regulation is essential.
