The Sun Hydraulics DDHCXYV (DDHCXYV) is a high-capacity, three-position, 4-way directional cartridge valve featuring spring-centered, 6-port configurations with a variety of spool options to suit different operational requirements. This model is designed to operate under a maximum pressure of 5000 psi (350 bar) across all ports, including the x and y pilot ports (port 5 and port 6). Each port's capacity is determined by the specific spool type chosen. The DDHCXYV incorporates hardened spool and sleeve components which ensure low leakage rates and superior wear characteristics, enhancing the valve's durability and performance consistency. This model benefits from Sun's floating style construction which minimizes internal parts binding that could occur due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum flow capacity of 80 gpm (320 L/min), with a minimum pilot pressure requirement of 200 psi (14 bar) necessary to shift the valve. The valve also features a maximum leakage rate at 110 SUS (24 cSt) of 5 in\u00b3/min at 1000 psi (80 cc/min at 70 bar), ensuring efficient operation even under demanding conditions. The pilot volume displacement stands at approximately .26 in\u00b3 (4.3 cc). For installation, the valve has a hex size of 1-5/8 inches (41.3 mm) and requires an installation torque between 350 - 375 lbf\u00b7ft (474 - 508 Nm). The overall weight of the model is relatively light at approximately 5.9 lbs (2.7 kg). Additionally, for maintenance or repairs, there is an available Viton seal kit specified as part number: 990054006.
