The Sun Hydraulics DDHGXZN (DDHGXZN) is a two-position, 3-way directional cartridge valve, distinguished by its robust design that includes a hardened spool and sleeve to ensure low leakage rates and superior wear characteristics. This model is part of the T-54A cavity series and falls under the 4 series category. It boasts a substantial capacity of up to 80 gpm (320 L/min), with a maximum operating pressure of 5000 psi (350 bar). The valve's design incorporates Sun's floating style construction, which reduces the risk of internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a minimum pilot pressure requirement of 300 psi (20 bar) for valve shifting, and a pilot pressure of 350 psi (24 bar) is necessary for full shift at rated flow. The maximum valve leakage at 110 SUS (24 cSt) is noted as 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar). Additionally, this model has a pilot volume displacement of .27 in\u00b3 (4.4 cc), and it requires an installation torque between 350 - 375 lbf\u00b7ft (474 - 508 Nm). The physical aspects are also notable with a hex size of 1-5/8 in. (41.3 mm) and an overall weight of approximately 5.9 lb (2.7 kg). This model uses Viton seals, ensuring high compatibility with various hydraulic fluids and enhancing its operational reliability under diverse conditions. The DDHGXZN valve is ideally suited for applications requiring reliable performance in shifting hydraulic flow directions under high-pressure conditions. Its design ensures minimal leakage and consistent operation, making it an essential component for high-demand hydraulic systems.
