The Sun Hydraulics DMDADRV236 (DMDADRV236) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures reliable control of hydraulic flow with its fatigue-rated solenoid tube assembly for 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. This model operates effectively without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. The manual override feature included in models with D or L control is specifically designed for temporary actuation, supported by a detent mechanism that sustains approximately 7,000 cycles of mechanical life. Additionally, the cartridge configured with EPDM seals is tailored for systems using phosphate ester fluids, avoiding compatibility issues with petroleum-based substances which could degrade the seals. The DMDADRV236 employs a wet armature design wherein the working fluid surrounds the armature to manage heat during prolonged coil energization\u2014a critical design consideration when using water-glycol mixtures that may degrade under high temperatures. Furthermore, its coils are interchangeable within Sun Series 1 solenoid products and can be oriented in either direction upon mounting. Incorporating Sun\u2019s floating style construction minimizes internal binding risks caused by excessive installation torque or variations in cavity/cartridge machining. This careful engineering ensures enhanced durability and reliability of the valve in demanding operational conditions. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and swift response times typically around 50 ms, the Sun Hydraulics DMDADRV236 is crafted to meet rigorous industrial requirements while maintaining precise control and functionality.

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.
