The Sun Hydraulics DMDALRN836 (DMDALRN836) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a robust design with a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service. It incorporates an innovative closed transition between Spools B and R during operation, enhancing performance by providing faster and more consistent response times especially suited for applications where pilot control and speed are critical. The DMDALRN836 is designed to operate without minimum hydraulic pressure, making it highly effective in various fluid power applications. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids. The wet armature design of the valve ensures that the working fluid surrounds the armature which can be crucial in managing heat during prolonged energization of the coil. This model also boasts interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. The construction utilizes Sun\u2019s floating style to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, this valve ensures efficient operation under demanding conditions. Furthermore, the manual override feature requires minimal force and has a stroke limit, ensuring temporary actuation is user-friendly and safe. The DMDALRN836 is also built to withstand up to 15,000 switching cycles per hour, demonstrating its capability to handle high-frequency operations reliably. This model's practicality extends through easy integration with existing systems due to its standard T11A cavity requirement and compatibility with various manual control assemblies like D, L, or T models for versatile application across different hydraulic setups.

This solenoid-operated 3-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.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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 configured 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
