The Sun Hydraulics RVCACDN (RVCACDN) is a ventable, pilot-operated, balanced piston relief cartridge designed for effective pressure regulation in hydraulic systems. This normally closed valve opens to the tank port 2 when inlet port 1 reaches a predetermined pressure, allowing it to throttle flow and maintain consistent pressure levels. It features a vent port 3 that connects between the main piston and pilot stage for remote control capabilities using other pilot or two-way valves. Known for its accuracy and low-pressure rise versus flow, the RVCACDN operates smoothly and quietly with moderate speed. This cartridge can handle maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. It is not recommended for load-holding applications due to potential spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen. The valve's back pressure at tank port 2 directly adds to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, EPDM seals are available but should not be exposed to petroleum-based substances. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variations. The RVCACDN fits into Cavity T-11A Series 1 with a capacity of 15 gpm (60 L/min) and operates under a maximum pressure of 5000 psi (350 bar). It has an adjustable screw with specific hex sizes for both adjustment and locknut purposes, ensuring precise control over settings with defined torque requirements. The valve weighs approximately 0.40 lb (0.20 kg) and comes with optional Viton seal kits for enhanced durability in various fluid conditions.

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.
