The Sun Hydraulics DMDADNN236 (DMDADNN236) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and precise control in hydraulic systems. Featuring a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, it ensures durability and reliability under high-pressure conditions. The valve's spools\u2014B and R\u2014are closed during the transition between positions, enhancing performance by providing faster and more consistent response times especially when used as pilot controls. The DMDADNN236 operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It includes options such as D or L control with a detent mechanism in the manual override meant for temporary actuation, supporting approximately 7,000 cycles of mechanical life expectancy. Notably, cartridges equipped with EPDM seals are specifically designed for use with phosphate ester fluids; however, they must be protected from exposure to petroleum-based fluids which can damage the seals. This model also incorporates a wet armature design where the working fluid surrounds the armature. This feature needs consideration as prolonged energization of the coil can lead to fluid breakdown in certain conditions like when using water-glycol mixtures. Moreover, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Other technical specifications include a flow capacity of up to 12 gpm (45 L/min), typical response time of 50 ms, maximum valve leakage at 3000 psi rated at 5 in\u00b3/min., and a switching frequency of up to 15,000 cycles/hr. The valve also features Sun's floating style construction that minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. This engineering attention to detail ensures that the DMDADNN236 provides reliable and efficient performance in demanding hydraulic applications.

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.
