The Sun Hydraulics DNDCXYN912 (DNDCXYN912) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient flow control in hydraulic systems. This valve is spring-centered to the neutral position and features two distinct flow paths depending on which coil is energized. When coil A is activated, the flow direction is 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. Engineered for robustness, the solenoid tube assembly can withstand fatigue at service pressures up to 5000 psi (350 bar). Notably, this valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The DNDCXYN912 utilizes a wet armature design that immerses the armature in working fluid, which can be advantageous or detrimental depending on fluid compatibility and temperature exposure. EPDM seals are incorporated for use with phosphate ester fluids; however, they should not contact petroleum-based fluids as this may cause degradation. The valve offers multiple coil termination and voltage configurations with optional surge protection\u2014details of which are available in the CONFIGURATION section. This model benefits from a high-efficiency solenoid that delivers substantial spool actuating force per watt of energy used. Coils are interchangeable among Sun Series 1 products and can be mounted bi-directionally on the tube. Additionally, connector options provide protection ratings up to IP69K for enhanced durability against environmental factors. The DNDCXYN912's design includes Sun's floating style construction to mitigate internal component binding due to installation torque or machining variances. It has a capacity of handling flows up to 5 gpm (20 L/min) with typical response times around 50 ms and maximum leakage rates at specified conditions of about 10 in\u00b3/min (160 cc/min).

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.
