The Sun Hydraulics FRDBLBV (Material Number: FRDBLBV) is a 2-port restrictive flow control valve designed to fit into a 3-port cavity, with no connection to port 2. This valve is ideal for applications requiring precise flow regulation, as it features a sharp-edged orifice design that minimizes flow variations due to viscosity changes. The unit allows customers to specify a factory-set flow rating with an accuracy claim of \u00b110%, but typically set within \u00b15% during production testing. It supports a tuneable adjustment control option providing up to 25% variation from the nominal factory preset flow, which can be adjusted using three turns of the adjust screw. The maximum pressure at port 3 should not exceed 3000 psi (210 bar), while the valve itself can handle maximum operating pressures up to 5000 psi (350 bar) and maximum input flows of 30 gpm (120 L/min). Constructed with Sun's floating style design, it minimizes the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The valve features a T-2A cavity and has a capacity of 12 gpm (45 L/min). Additional specifications include a valve hex size of 1-1/8 inches (28.6 mm), an adjustment screw internal hex size of 5/32 inches (4 mm), and a locknut hex size of 9/16 inches (15 mm), with installation torque requirements ranging from 45-50 lbf ft (61-68 Nm) for the valve and locknut torque between 80-90 lbf in (9-10 Nm). The model weighs approximately .40 lb (.20 kg) and uses Viton seal kits for cartridge sealing.
