The Sun Hydraulics RPIDBBV (RPIDBBV) is an air-controlled, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This valve utilizes compressed air over a diaphragm to control the pressure setting instead of an adjustable spring, making it suitable for applications requiring smooth and quiet operation with moderate speed. It is typically used in systems where accurate pressure control is essential, such as cross port relief circuits. The valve is normally closed and begins to open to tank port 2 when the inlet port 1 pressure reaches the set value, throttling flow to maintain the desired pressure. The RPIDBBV can handle maximum pressures of up to 2000 psi (140 bar) and operates with a maximum air pressure of 150 psi (10.5 bar). Its design incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or machining variations. The valve features a cavity size of T-16A/S3 with a capacity of 100 gpm (380 L/min) and has a pilot ratio of 20:1. It offers low hysteresis with dither and typical response times around 10 ms. Physically and functionally interchangeable across frame sizes, this cartridge provides versatility in various hydraulic systems. The maximum valve leakage at 110 SUS (24 cSt) is specified at 4 in\u00b3/min (65 cc/min) under a pressure of 1000 psi (70 bar). Installation requires a valve hex size of 1\u00bc inches (31.8 mm) with torque specifications between 150 and 160 lbf ft (203 to 217 Nm). Weighing approximately 1.20 lbs (0.55 kg), the RPIDBBV comes equipped with Viton seals for enhanced durability in demanding environments.
