The Sun Hydraulics RVBACNN (Material Number: RVBACNN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve begins to open when the inlet port pressure reaches the set threshold, directing flow to tank port 2 and maintaining consistent pressure levels. It features a vent port that allows for remote control via other pilot or two-way valves, offering versatility in system integration. The valve is recognized for its accuracy, low-pressure rise relative to 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 minimum setting is 75 psi (5 bar) across all spring ranges. Due to potential spool leakage, it's not recommended for load-holding applications. Back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. The main stage orifice is contamination-protected and incorporates Sun's floating style construction to prevent binding from excessive torque or machining variations in installation. Key specifications include a cavity T-163A series with a capacity of 7.5 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), and control pilot flow between 7-10 in\u00b3/min (0.11-0.16 L/min). Typical response time is around 10 ms with maximum valve leakage at 2 in\u00b3/min under specified conditions. The adjustment mechanism involves a number of clockwise turns to increase settings by approximately five turns, with specific hex sizes provided for various components involved in installation and adjustment processes. Weighing .30 lb (.15 kg), it uses Viton seal kits for optimal performance and durability.

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.
- Minimum setting is 75 psi (5 bar) for all spring ranges.
- 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.
- The main stage orifice is protected against contamination.
- 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.
