The Sun Hydraulics DNDAXEN836 (DNDAXEN836) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered for high performance, with a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), offering reliable service without requiring minimum hydraulic pressure for operation. It features multiple manual override options, though note that manual overrides are incompatible with weatherized coils. The D and L control models include a detent mechanism intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This cartridge is particularly suited for systems utilizing phosphate ester fluids when equipped with EPDM seals; exposure to petroleum-based fluids can damage these seals. The valve's wet armature design allows the working fluid to cool the armature while being exposed to coil-generated heat\u2014an important consideration during prolonged coil energization as certain fluids may deteriorate under these conditions. The solenoid's magnetic design enhances efficiency, providing high spool actuating force per watt consumed for dependable valve shifting. Coil options are extensive, including various terminations and voltages with or without surge protection, and are interchangeable within the Sun Series 1 solenoid products. The DNDAXEN836 incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It fits into a T-31A cavity and belongs to Series 1, with a capacity of up to 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar). The typical response time is 50 ms, and it supports switching frequencies up to 15,000 cycles per hour. Additional specifications include a valve hex size of .78 in (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm).

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.
