The Sun Hydraulics DCDADHN (DCDADHN) is a three-position, 4-way directional cartridge valve featuring spring-centered control and a 6-port configuration. This model is versatile with 10 different spool options available to tailor its function according to specific application needs. Each port, including the supply port (port 1) as well as the x and y pilot ports (port 5 and port 6), can handle up to 5000 psi or 350 bar. The capacity of this pilot-to-shift valve varies depending on the spool type selected. The DCDADHN model is designed for robust performance with hardened spool and sleeve that ensure low leakage rates and high wear resistance, contributing to consistent operation and longevity. Additionally, it incorporates Sun\u2019s floating style construction which reduces the risk of internal parts binding\u2014a common issue that can occur due to excessive installation torque or variations in cavity/cartridge machining. Technical specifications include a flow capacity ranging from 11 to 30 gpm (38 to 120 L/min), with a minimum pilot pressure requirement of 150 psi (10.5 bar) for valve shifting. It supports a maximum operating pressure of up to 5000 psi (350 bar). Leakage specifications indicate a maximum of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The valve features a hex size of 1-1/8 inches (28.6 mm) and requires an installation torque between 45-50 lbf\u00b7ft (61-68 Nm). The unit\u2019s weight stands at approximately .80 lb (0.35 kg). For maintenance, a Viton seal kit is recommended, specifically part number: 990062006.
