The Sun Hydraulics DNDCXBV736 (DNDCXBV736) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This innovative valve offers versatile flow control, where energizing coil A channels flow from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. Designed for demanding applications, the solenoid tube assembly supports up to 5000 psi (350 bar), making it suitable for high-pressure environments without requiring minimum hydraulic pressure for operation. The valve's construction includes a wet armature design, enhancing reliability by allowing working fluid exposure around the armature. This feature, however, necessitates careful fluid selection as some fluids like water-glycol mixtures may degrade over time due to heat exposure. The DNDCXBV736 accommodates various coil termination and voltage options with surge protection capabilities, offering flexibility in installation and environmental protection with IP69K-rated coil connectors. Sun Hydraulics' unique magnetic design ensures efficient operation by delivering high spool actuating force per watt expended. The interchangeable coils can be mounted in either direction on the tube and are compatible with other Sun Series 1 solenoid products. Additional weatherized coils and kits are available for enhanced environmental resilience. With a capacity of up to 5 gpm (20 L/min) and a typical response time of approximately 50 ms, this valve is engineered for rapid switching at frequencies up to 15,000 cycles per hour. The DNDCXBV736 incorporates Sun's floating style construction which minimizes internal binding risks due to installation torque or machining variations in cavity/cartridge interfaces. For optimal performance in differential flow circuits, directing higher return flow through specified ports is recommended.

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.
