The Sun Hydraulics DNDCXHN936 (DNDCXHN936) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision fluid control. This valve is spring-centered to a neutral position and can be operated by energizing one of two coils. When coil A is activated, the flow direction changes 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 valve is engineered for high-pressure applications with a fatigue rating of up to 5000 psi (350 bar), ensuring durability in demanding environments. This model does not require minimum hydraulic pressure for operation due to its direct actuation design. It features a wet armature solenoid design that allows the working fluid to surround the armature, which can influence performance if the coil remains energized over prolonged periods. The valve is compatible with EPDM seals for use with phosphate ester fluids; however, caution should be taken as exposure to petroleum-based fluids could damage these seals. The DNDCXHN936 offers versatility with various coil termination and voltage options available, some providing surge protection and weatherized solutions up to IP69K rating for enhanced environmental protection. The solenoid's magnetic design ensures efficient power usage while delivering reliable valve shifting capabilities. This valve incorporates Sun's floating style construction which reduces potential binding issues due to installation torque or machining variations. Additional specifications include a cavity size of T31A, series number 1, capacity of up to 5 gpm (20 L/min), typical response time of 50 ms, maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), and switching frequency capability of up to 15,000 cycles/hr. The installation requires specific torque settings and offers interchangeable coil compatibility within Sun Series 1 products.

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.
