The Sun Hydraulics RVGAMFV (Material Number: RVGAMFV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This valve remains normally closed and opens to tank port 2 when the inlet port 1 pressure reaches the set threshold, allowing it to throttle flow and maintain desired pressure levels. It includes a vent port 3 for remote control by other pilot or two-way valves, enhancing its adaptability. Known for accuracy and smooth operation, this valve features a low-pressure rise versus flow and moderate response speed. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits while considering spool leakage. However, it's not ideal for load-holding applications due to this leakage characteristic. The main stage orifice is safeguarded by a 150-micron stainless steel screen. The valve's design incorporates Sun's floating style construction to minimize binding risks from installation torque or machining variations. It operates effectively in systems using phosphate ester fluids with EPDM seals but is incompatible with petroleum-based fluids as they can damage these seals. Its capacity reaches up to 60 gpm (240 L/min) with a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are 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 around 10 ms. Additional specifications include a maximum valve leakage of 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar), adjustment capability via an internal hex screw, and specific torque requirements for installation and locknut adjustments. The model weighs approximately 1.60 lb (0.70 kg) and comes with a Viton seal kit option for enhanced durability in suitable fluid environments.

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.
