The Sun Hydraulics DMDADBN236 (DMDADBN236) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a robust design that requires no minimum hydraulic pressure for operation, making it highly effective in a variety of applications. Its solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The DMDADBN236 valve is equipped with spools B and R that are closed during the transition between positions, which enhances performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The valve also incorporates a manual override with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles. Designed with user convenience in mind, this model utilizes interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also features Sun's floating style construction to minimize internal part binding due to installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar), the DMDADBN236 offers efficient fluid control. The valve's response time is typically around 50 ms, and it can handle switching frequencies up to 15,000 cycles per hour. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids. This model also benefits from a wet armature design where the working fluid surrounds the armature to manage heat during prolonged coil energization effectively.

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.
