The Sun Hydraulics DNDCXTE612 (DNDCXTE612) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve is designed for high-efficiency operation, with a unique magnetic design that provides high spool actuating force per watt expended. It operates with no minimum hydraulic pressure required and has a maximum operating pressure of 5000 psi (350 bar). When coil A is energized, the flow transitions from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. The DNDCXTE612 features a wet armature design where the working fluid surrounds the armature, which can influence fluid stability if the coil is energized for extended periods. This design consideration is crucial for systems using fluids like water-glycol mixtures that may degrade over time at elevated temperatures. The valve's construction incorporates Sun's floating style to minimize potential binding of internal parts due to excessive installation torque or cavity-cartridge machining variations. This model supports differential flow circuits by directing higher return flows through specific ports and offers multiple coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connector options are rated up to IP69K, providing robust environmental protection. The valve also boasts a fatigue-rated solenoid tube assembly suitable for demanding applications. With a capacity of handling up to 5 gpm (20 L/min) and typical response times around 50 ms, this valve is suitable for applications requiring rapid and reliable directional control. Its compact design includes a solenoid tube diameter of .75 in (19 mm) and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). Seal kits are available in Viton material for enhanced durability against various fluids.

This direct acting, solenoid-operated, 4-way, 3-position spool valve is spring centered to the neutral position. When coil A is energized, the flow is from port 3 (P) to port 2 (A) and from port 4 (B) to port 1 (T). When coil B is energized, the flow is from port 3 to port 4 and from port 2 to port 1.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- In differential flow circuits, the higher return flow should be directed through port 2 (A) to port 1 (T).
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- 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.
