The Sun Hydraulics RVIAKWV (RVIAKWV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve remains closed until the inlet port pressure reaches a predetermined setting, at which point it opens to the tank port, throttling flow to maintain consistent pressure levels. It features a vent port that allows remote control via other pilot or two-way valves. Known for its accuracy and smooth operation, the RVIAKWV is suitable for applications requiring moderate speed and low-pressure rise versus flow. It can handle maximum pressure at port 2, making it ideal for cross-port relief circuits, although spool leakage should be considered in such setups. The main stage orifice is safeguarded by a 150-micron stainless steel screen to ensure reliability and longevity. However, it is important to note that this valve is not recommended for load-holding applications due to potential spool leakage. The cartridge can be equipped with EPDM seals for systems utilizing phosphate ester fluids but should not be exposed to petroleum-based substances as they may damage the seals. Incorporating Sun's floating style construction minimizes the risk of internal part binding due to excessive installation torque or machining variations. The RVIAKWV has a cavity size of T-19A and belongs to Series 4 with a capacity of up to 120 gpm (480 L/min). It operates at a maximum pressure of 5000 psi (350 bar), with control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time around 10 ms. The valve features an adjustable setting with up to five clockwise turns needed for increasing settings and requires specific installation and locknut torque specifications for optimal performance.

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.
- Relief valve setting must always be higher than pilot valve setting.
- Not suitable for use in load holding applications due to spool leakage.
- 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.
