The Sun Hydraulics DNDCXHV612 (DNDCXHV612) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This valve allows for precise control of hydraulic flow; when coil A is energized, it directs flow from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is designed for high durability, rated for service at pressures up to 5000 psi (350 bar), ensuring dependable performance in demanding applications. This valve requires no minimum hydraulic pressure for operation and features a wet armature design that immerses the armature in working fluid, which can affect fluid stability under prolonged coil energization. It's crucial for users employing water-glycol mixtures to consider potential varnish formation due to heat exposure. The DNDCXHV612 offers versatility with a range of coil termination and voltage options available, including those with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. The unique magnetic design of the solenoid provides high efficiency by maximizing spool actuating force relative to power consumption. Environmental protection is enhanced through various coil connector options rated up to IP69K and additional weatherized coils and kits. This valve uses Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. It fits into cavity T-31A, has a capacity of up to 5 gpm (20 L/min), typical response time of 50 ms, and a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The recommended installation torque ranges between 30-35 lbf ft (41-47 Nm). Seal kits are available in Viton material for both cartridge and coil components.

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.
