The Sun Hydraulics RVBACWN (RVBACWN) is a ventable, pilot-operated, balanced piston relief cartridge designed to regulate pressure in hydraulic systems. This normally closed pressure regulating valve opens to the tank port when the inlet pressure reaches the valve's set threshold, throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control via other pilot or 2-way valves, enhancing its versatility in various applications. The RVBACWN is known for its accuracy and smooth operation, with low pressure rise relative to flow and moderately fast response times. It can accept maximum pressure at port 2 and is suitable for use in cross-port relief circuits; however, users should consider spool leakage in such configurations. The minimum setting for all spring ranges is 75 psi (5 bar), and it is not recommended for load holding applications due to potential spool leakage. 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 its construction minimizes internal binding risks from installation torque or machining variations. This model has a cavity size of T-163A and a series capacity of 7.5 gpm (30 L/min). It operates at pressures up to 5000 psi (350 bar) with control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min). Typical response time is approximately 10 ms, with maximum valve leakage at specified conditions being 2 in\u00b3/min (30 cc/min). Installation requires specific torques for adjustment screws and locknuts, ensuring proper setup and function within hydraulic systems.
