The Sun Hydraulics RVGAKFV (RVGAKFV) is a ventable, pilot-operated, balanced piston relief cartridge designed to regulate pressure in hydraulic systems. This valve is normally closed and opens to tank port 2 when the inlet port 1 pressure reaches the set level, effectively throttling flow to maintain desired pressure levels. It features a vent port 3 that allows for remote control via other pilot or two-way valves. The RVGAKFV is known for its accuracy, low pressure rise versus flow, smooth operation, and moderate speed. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability. It is not recommended for load-holding applications due to potential spool leakage. Notably, back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. The cartridge can be configured with EPDM seals for systems using phosphate ester fluids but should not be exposed to petroleum-based products as they can damage the seals. The valve incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or machining variations in cavity/cartridge setups. It fits Cavity T-17A with a Series 3 capacity of up to 60 gpm (240 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The control pilot flow ranges between 15-20 in\u00b3/min (0.25-0.33 L/min) with a typical response time of 10 ms. Maximum valve leakage at standard conditions is specified as 4 in\u00b3/min (65 cc/min). Installation requires specific torques for both the valve body and adjustment components, enhancing secure fitting and operational stability.

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.
