The Sun Hydraulics RVGALYV (RVGALYV) 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 pressure reaches its set point, at which time it opens to the tank port to throttle flow and maintain the desired pressure. It features a vent port that allows remote control by other pilot or two-way valves, offering versatility in various applications. With a capacity of 60 gpm (240 L/min) and maximum operating pressure of 5000 psi (350 bar), this cartridge is suitable for cross-port relief circuits, though spool leakage should be considered in such configurations. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability. However, it is not recommended for load-holding applications due to potential spool leakage. The valve's setting can be influenced by back pressure on the tank port at a 1:1 ratio. Cartridges with EPDM seals are compatible with phosphate ester fluids but may be damaged by petroleum-based substances. Sun Hydraulics' floating style construction minimizes internal binding risks due to installation torque or cavity machining variations. The RVGALYV model has factory pressure settings established at 4 gpm (15 L/min), with control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time of 10 ms. Maximum valve leakage is rated at 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Adjustments are made via an internal hex screw, requiring specific torque settings for installation and locknut adjustments. The model weighs approximately 1.60 lbs (0.70 kg) and comes with a Viton seal kit option for enhanced performance under various conditions.

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.
