The Sun Hydraulics RVGALFV (Material Number: RVGALFV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve remains normally closed until the inlet port pressure reaches the set threshold, at which point it begins to open to the tank port, throttling flow to maintain desired pressure levels. It features a vent port that enables remote control via other pilot or two-way valves. The RVGALFV is noted for its accuracy, low pressure rise versus flow characteristics, smooth operation, and moderate speed response. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should be aware of potential spool leakage in such applications. The main stage orifice benefits from protection by a 150-micron stainless steel screen, ensuring durability and reliability. However, this cartridge is not recommended for load-holding applications due to potential spool leakage. It\u2019s important to note that back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are available; however, these should not be exposed to petroleum-based substances as they may cause damage. This model incorporates Sun's floating style construction to reduce risks of internal part binding due to excessive installation torque or machining variations. With a capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar), this cartridge offers robust performance in demanding environments. The factory settings are established at 4 gpm (15 L/min) with an adjustment capability of up to 5-5 turns clockwise for increased settings. The valve's compact design includes specific installation torque requirements and comes with Viton seal kits for enhanced longevity and performance in various applications.
