The Sun Hydraulics RVBALAN (Material Number: RVBALAN) is a ventable, pilot-operated, balanced piston relief cartridge. This normally closed pressure regulating valve is designed to open to tank port 2 when the inlet port 1 pressure reaches the valve setting, thus throttling flow to regulate pressure. It features a vent port 3 that allows for remote control by other pilot or two-way valves. This valve is known for its accuracy, smooth and quiet operation, and moderate speed. It can accept maximum pressure at port 2 and is suitable for cross-port relief circuits, although spool leakage should be considered in such applications. The minimum setting for all spring ranges is 75 psi (5 bar), but it is not recommended for load holding applications due to potential spool leakage. Additionally, any back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. The RVBALAN model incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations in the cavity or cartridge. It has a capacity of 7.5 gpm (30 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min), with a typical response time of 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is specified as 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Installation requires a torque of 20-25 lbf ft (27-33 Nm), with adjustment made via an internal hex screw size of ^5/32 inch (4 mm). The model weighs approximately .30 lb (.15 kg) and includes a Viton seal kit option under part number: 990163006.
