The Sun Hydraulics RVIACAN (Material Number: RVIACAN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. These normally closed valves begin to open to tank port 2 when the inlet pressure at port 1 reaches the set threshold, thereby throttling flow to maintain the desired pressure level. A vent port (port 3) allows for remote control via other pilot or two-way valves, making these cartridges versatile in various applications. They are known for their accuracy, low pressure rise versus flow, smooth operation, and moderate speed. The valve can accept maximum pressure at port 2 and is suitable for cross-port relief circuits\u2014though spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. However, these cartridges are not recommended for load-holding applications due to potential spool leakage. Cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; exposure to petroleum-based substances will damage these seals. The floating style construction minimizes the risk of internal component binding due to excessive installation torque or machining variations. This Series 4 cartridge has a capacity of up to 120 gpm (480 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The factory settings are established at 4 gpm (15 L/min), with a control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min). Typical response time is around 10 ms, and maximum valve leakage at specified viscosity is approximately 5 in\u00b3/min (80 cc/min). The model weighs approximately 3.10 lb (1.40 kg), with specific installation and adjustment specifications detailed in its technical data sheet.

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.
