The Sun Hydraulics DNDAXRV936 (DNDAXRV936) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to handle high-pressure applications with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. It operates without requiring any minimum hydraulic pressure and offers various manual override options, although manual overrides are not compatible with weatherized coils. The DNDAXRV936 features a wet armature design that ensures the working fluid effectively dissipates heat generated by the coil, which is crucial for long-term operation in certain fluid types like water-glycol mixtures that can degrade at high temperatures. This model also includes Sun's innovative floating style construction to prevent internal part binding due to installation torque or machining variations. The valve's high-efficiency solenoid provides substantial spool actuating force per watt, ensuring reliable valve shifting performance. It supports a range of coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. The available coil connector options offer protection ratings up to IP69K for enhanced environmental resilience. With a capacity of 10 gpm (40 L/min), it maintains maximum operating pressure up to 5000 psi (350 bar) and has a typical response time of 50 ms. Its switching frequency can reach up to 15,000 cycles per hour, making it suitable for dynamic applications requiring rapid actuation cycles. The valve's maximum leakage rate is kept minimal at 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar). Installation requires a torque between 30 and 35 lbf\u00b7ft (41 to 47 Nm), ensuring secure fitting in its T-31A cavity configuration.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
