The Sun Hydraulics FRDBLBN (Material Number: FRDBLBN) is a 2-port restrictive flow control valve designed for insertion into a 3-port cavity, specifically the T-2A cavity. This model effectively operates by leaving port 2 of the cavity unconnected. Users must specify a desired flow rating, with factory settings accurate within \u00b110% of this request. The valve can handle a maximum pressure at port 3 of up to 3000 psi (210 bar). Its sharp-edged orifice design ensures minimal flow variation due to viscosity changes, making it reliable under varying conditions. Additionally, it features a tunable adjustment control allowing for up to a 25% variation from the nominal preset flow, adjustable with three turns of an internal hex screw. The FRDBLBN incorporates Sun's floating style construction, which reduces the risk of internal part binding due to excessive installation torque or machining variations in the cavity or cartridge. It has a capacity of 12 gpm (45 L/min) and can accommodate maximum input flows up to 30 gpm (120 L/min). The valve's hex size is 1-1/8 inches (28.6 mm), and it should be installed with a torque between 45 and 50 lbf\u00b7ft (61 and 68 Nm). For adjustments, the internal hex size is 5/32 inches (4 mm), and the locknut requires a torque between 80 and 90 lbf\u00b7in (9 and 10 Nm). This model weighs approximately .40 lb (.20 kg) and uses Viton seals with part number 990202006 for its cartridge seal kit. The FRDBLBN is ideal for applications requiring precise flow control in hydraulic systems where maintaining consistent performance across varying conditions is critical.
