The Sun Hydraulics DNDCXTE836 (DNDCXTE836) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic flow control. This valve is spring-centered to the neutral position and offers versatile flow paths depending on the coil that is energized. When coil A is activated, the flow redirects from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B allows flow from port 3 to port 4 and from port 2 to port 1. Engineered for durability, the solenoid tube assembly can withstand a fatigue-rated pressure of up to 5000 psi (350 bar), ensuring reliable performance in demanding applications. This valve operates without requiring any minimum hydraulic pressure and is particularly suited for differential flow circuits where higher return flows should be routed through specific ports. It features a wet armature design that helps dissipate heat generated during prolonged coil energization; however, users should be cautious with fluids like water-glycol mixtures that may degrade under such conditions. The DNDCXTE836 includes flexible options for coil termination and voltage configurations, along with interchangeable coils compatible with other Sun Series 1 solenoid products. It supports various environmental conditions with coil connector ratings up to IP69K and additional weatherized options for enhanced protection. With a capacity of up to 5 gpm (20 L/min) and a quick response time of approximately 50 ms, this valve provides efficient operation in high-frequency switching applications\u2014up to 15,000 cycles per hour. The design incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. The valve also comes equipped with Viton seal kits for both cartridge and coil components, ensuring compatibility with diverse fluid types while offering robust sealing performance.

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.
