The Sun Hydraulics RVBAKAN (RVBAKAN) is a ventable, pilot-operated, balanced piston relief cartridge designed as a normally closed pressure regulating valve. It functions by opening to the tank port when the inlet pressure reaches the valve setting, allowing throttling flow to regulate pressure. This model features a vent port that facilitates remote control through other pilot or 2-way valves. Notably accurate and smooth in operation, it also boasts low pressure rise versus flow and moderate speed. The relief valve can be controlled below its setting via a remote pilot relief on the vent port. It can accept maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The minimum setting for all spring ranges is 75 psi (5 bar), and it is not recommended for load holding due to leakage concerns. Back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. The design incorporates Sun's floating style construction, which helps prevent internal binding from excessive torque or machining variations. It features a protected main stage orifice against contamination and uses Cavity T-16A with a series 0 capacity of 7.5 gpm (30 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with a typical response time of 10 ms. Maximum valve leakage at 110 SUS is specified as 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Installation requires specific torque settings for both the valve and locknut, with detailed adjustment specifications provided for fine-tuning settings using an internal hex screw and locknut configuration.
