    The document describes a direct-acting relief valve model RGFA SERIES 2 used to protect hydraulic components from pressure. It has a capacity of 200 L/min and works in a T-3A cavity. When pressure at the inlet port reaches the valve setting, it starts to open and throttle flow to tank to limit pressure rise. Technical data and configuration options are provided, along with notes on installation and performance curves.

    MODEL Low-pressure-range, direct-acting relief valve

    RGFA SERIES 2 / CAPACITY: 200 L/min. / CAVITY: T-3A

    sunhydraulics.com/model/RGFA

    Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components
    from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open
    to tank (port 2), throttling flow to limit the pressure rise.

    TECHNICAL DATA NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.

    TECHNICAL FEATURES
    All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
    Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
    Not suitable for use in load holding applications due to spool leakage.
    Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
    Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel
    components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of
    Construction page located under TECH RESOURCES.
    Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
    machining variations.
