The Sun Hydraulics FRDCXAV (Material Number: FRDCXAV) is a specialized flow control valve designed to operate in bypass mode only, with modifications aimed at enhancing system stability under specific conditions. It is based on the FRDA model and features a design that ceases pressure compensation for priority flow when bypass pressure surpasses the priority port pressure. This valve requires specification of a flow rating by the customer, with factory settings accurate within 10% of the desired rate. The maximum allowable pressure at port 3 is 3000 psi (210 bar), and bypass flow only commences once priority flow needs are met. The valve employs a sharp-edged orifice design to minimize variations in flow caused by changes in fluid viscosity. For added flexibility, it includes an adjustable control option permitting up to a 25% variation from the nominal factory preset flow, adjustable via a screw mechanism with three turns. The Sun floating style construction minimizes risks of internal part binding due to excessive installation torque or machining variations. Key specifications include a capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and maximum input flow of 30 gpm (120 L/min). It fits into a T2A cavity, has a series designation of 2, and measures 1-1/8 inches (28.6 mm) across its hex size. Installation torque ranges between 45 to 50 lbf ft (61 to 68 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut size is 9/16 inches (15 mm) with a torque requirement of 80 to 90 lbf in (9 to 10 Nm). The model weighs approximately .40 lb (.20 kg) and uses Viton seal kit number 990202006.
