The Sun Hydraulics RVGALEV (Material Number: RVGALEV) 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 specified setting, at which point it opens to the tank port, effectively throttling flow to maintain the desired pressure level. The valve features a vent port that enables remote control by other pilot or two-way valves, offering enhanced control flexibility. Known for its accuracy and smooth operation, this valve exhibits low pressure rise relative to flow and operates quietly with moderate response speed. The RVGALEV is engineered to accept maximum pressure at port 2 and is suitable for cross-port relief circuits, although users should account for potential spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliable performance. However, it is not recommended for load-holding applications due to potential leakage. The back pressure on the tank port adds directly to the valve setting at a 1:1 ratio. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are available; exposure to petroleum-based fluids can damage these seals. The valve employs Sun's floating style construction to reduce internal part binding risks from excessive installation torque or cavity/cartridge machining variations. With a capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model supports adjustments via an internal hex screw and locknut. Installation requires specific torque settings for optimal performance. The RVGALEV weighs approximately 1.60 lb (0.70 kg) and comes with an optional Viton seal kit (Part Number: 990017006).

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.
