The Sun Hydraulics DNDCXHV636 (DNDCXHV636) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic flow control. This valve features a spring-centered neutral position and offers directional flow control based on coil energization: energizing coil A channels flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. Engineered for robustness, the solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring durability under demanding conditions. The valve's design does not require minimum hydraulic pressure for operation, making it versatile for various applications. In differential flow circuits, it is recommended that higher return flows are routed through port 2 A to port 1 T. The valve's wet armature design allows the working fluid to surround the armature, potentially impacting fluid stability if the coil remains energized over extended periods. This feature necessitates careful consideration of fluid type; EPDM seals should be used with phosphate ester fluids only, as exposure to petroleum-based substances can cause seal damage. The DNDCXHV636 boasts a high-efficiency solenoid with significant spool actuating force per watt expended, enhancing reliability in valve shifting. Compatibility with Sun Series 1 solenoid products allows interchangeable coils that can be mounted in any direction on the tube. Coil connector options are available with ratings up to IP69K for superior environmental protection. The valve incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations in cavity/cartridge setups. With a capacity of up to 5 gpm (20 L/min) and typical response time of around 50 ms, this valve ensures swift and efficient operation across numerous hydraulic systems.

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.
