The Sun Hydraulics DDDGXRV (Material Number: DDDGXRV) is a two-position, 3-way directional cartridge valve notable for its robust design and versatile applications in hydraulic systems. This model features six ports, although port 5 is not utilized, and can be configured with up to five different spool configurations to suit various operational requirements. The supply port for this valve is designated as port 3, and all ports are capable of handling pressures up to 5000 psi (350 bar). The performance of the DDDGXRV greatly depends on the spool type used, which also influences the pilot pressure required for shifting the valve. This valve offers a maximum flow capacity of 20 gpm (80 L/min) and requires a minimum pilot pressure of 145 psi (10 bar) to shift, with full shifting at rated flow requiring a pilot pressure of 290 psi (20 bar). It incorporates Sun Hydraulics' floating style construction which minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining. This design feature, along with hardened spool and sleeve, ensures low leakage rates and excellent wear characteristics. The maximum operating pressure for this valve stands at 5000 psi (350 bar), while its maximum leakage at 110 SUS (24 cSt) is noted as 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The DDDGXRV also features a compact pilot volume displacement of .05 in\u00b3 (0.82 cc), making it efficient in terms of fluid dynamics within hydraulic circuits. For installation, the valve hex size is specified as 1-1/8 inch (28.6 mm) with an installation torque range between 45 -50 lbf ft (61 -68 Nm). The seal kit compatible with this cartridge uses Viton components, ensuring durability and resistance against various types of fluids used within hydraulic systems.
