The Sun Hydraulics DCECXNV (DCECXNV) is a robust and versatile hydraulic component designed for high-pressure applications. This three-position, 4-way directional cartridge valve is spring-centered and features six ports, including pilot ports (port 5 and port 6) that are positively sealed from the work ports. Each port, including the supply port (port 3), can handle pressures up to 5000 psi (350 bar). The valve's performance varies with different spool configurations due to flow forces, which are proportional to the flow rate and pressure drop across the valve. These forces typically resist the opening of a passage, with configurations that open passages as they spring center being most susceptible to incomplete shifting if flow forces exceed the centering spring force. The DCECXNV offers flexibility in hydraulic system design with its capacity ranging from 25 to 100 gpm (95 to 380 L/min) and a minimum pilot pressure requirement of 125 psi (9 bar) for valve shifting. Maximum operating pressure for this model is consistently high at 5000 psi (350 bar). Leakage specifications indicate a maximum of 2 in\u00b3/min per 1000 psi (30 cc/min per 70 bar). Constructed with durability in mind, it incorporates hardened spool and sleeve for low leakage rates and excellent wear characteristics. Additionally, this model uses Sun's floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as they can damage the seals. The physical specifications include a hex size of 1\u00bc inches (31.8 mm), installation torque between 150 -160 lbf\u00b7ft (203 -217 Nm), and a weight of approximately 1.80 lbs (0.80 kg). This makes the DCECXNV an indispensable component for advanced hydraulic setups demanding precision and reliability under high-pressure conditions.

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.
