The Sun Hydraulics RVGALWV (RVGALWV) is a ventable, pilot-operated, balanced piston relief cartridge designed primarily for pressure regulation applications. This normally closed valve opens to tank port 2 when the pressure at inlet port 1 reaches the set threshold, allowing flow to be throttled and pressure to be regulated. It features a vent port 3 that facilitates remote control by other pilot or two-way valves. The RVGALWV is known for its accuracy, smooth operation, quiet performance, and moderate speed. The valve can accept maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is protected by a 150 micron stainless steel screen, but the valve is not recommended for load-holding applications due to potential spool leakage. Back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are intended for systems using phosphate ester fluids and should not be exposed to petroleum-based substances as this could damage the seals. The design incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. Key specifications include a capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 15-20 in\u00b3/min (0.25-0.33 L/min), with typical response times around 10 ms. Maximum valve leakage at specific conditions is rated at 4 in\u00b3/min (65 cc/min). Installation requires specific torque values and adjustments are made via an internal hex screw with up to five full turns needed to increase settings.

Ventable, pilot-operated, balanced piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
- A remote pilot relief on port 3 (vent) will control the valve below its own setting.
- 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.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- 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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
