The Sun Hydraulics DNDATEV636 (Material Number: DNDATEV636) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve boasts a fatigue-rated solenoid tube assembly suitable for service pressures up to 5000 psi (350 bar), ensuring robust performance without the need for minimum hydraulic pressure. It offers several manual override options, though compatibility with weatherized coils is limited. For models featuring D or L control, the manual override detent mechanism supports temporary actuation with an estimated mechanical life of approximately 7,000 cycles. This cartridge is particularly suited for systems utilizing phosphate ester fluids when equipped with EPDM seals; however, these seals are incompatible with petroleum-based substances. The valve employs a wet armature design that immerses the armature in working fluid, which can be impacted by prolonged coil energization\u2014especially in systems using water-glycol mixtures that may degrade under heat. The DNDATEV636 features a high-efficiency solenoid magnetic design that delivers reliable valve shifting through substantial spool actuating force per watt consumed. It offers interchangeable coils compatible with other Sun Series 1 products and can be mounted bidirectionally on the tube. Coil connector options provide IP69K ratings for enhanced environmental protection. Additional specifications include a T31A cavity configuration, a capacity of up to 10 gpm (40 L/min), and a typical response time of 50 milliseconds. The valve supports switching frequencies of up to 15,000 cycles per hour and has an installation torque range between 30 to 35 lbf-ft (41 to 47 Nm). With its floating style construction, this cartridge minimizes internal binding risks due to excessive installation torque or machining variations.

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.
