The Sun Hydraulics DCECXTV (DCECXTV) is a versatile three-position, 4-way directional cartridge valve characterized by its spring-centered mechanism and a configuration that supports six ports, each capable of handling up to 5000 psi (350 bar). This model is particularly noted for its robust design which includes hardened spool and sleeve to ensure low leakage rates and superior wear characteristics. The valve's capacity varies depending on the spool type chosen, influenced by flow forces which are proportional to flow and pressure drop. These forces can impact the shifting of the valve if they exceed the centering spring force, especially under conditions of high flow at lower pressures. The DCECXTV features pilot ports (port 5 and port 6) that are positively sealed from the work ports, enhancing its operational integrity. It is designed with EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, it incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Technical specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity ranging from 25 to 100 gpm (95 to 380 L/min), and minimal pilot pressure required for valve shifting at 125 psi (9 bar). The model also specifies leakage rates, pilot volume displacement, hex size for installation, and recommended installation torque settings. With a weight of approximately 1.80 lbs (0.80 kg), this model is engineered for precision and reliability in various hydraulic applications.

Three-position, 4-way directional cartridges are spring-centered, 6-port directional valves that can be configured from a choice of spool options. The supply port is port 3 and all ports will accept 5000 psi (350 bar). Capacity for these pilot-to-shift valves is dependent on the spool type specified.
- All ports will accept 5000 psi (350 bar), including the x and y pilot ports (port 5 and port 6).
- The reason for the different capacities, or performance limits, for the different spool configurations are flow forces. Flow forces are proportional to flow and pressure drop. Typically, they resist the opening of a passage. Spool configurations that open passages as they spring center are the most susceptible. If the flow forces due to the flow and pressure conditions exceed the centering spring force the valve may not shift completely. Higher flows may be used at lower pressures.
- Leakage listed in technical data is for each path.
- The pilot ports, 5 and 6, are positively sealed from the work ports.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Hardened spool and sleeve provide consistent and low spool leakage rates and excellent wear characteristics.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
