The Sun Hydraulics DMDAMNV236 (DMDAMNV236) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is fatigue rated for demanding applications, supporting up to 5000 psi (350 bar) service. Ideal for use as pilot controls, its closed transition between Spools B and R ensures fast and consistent response times without the need for minimum hydraulic pressure. This model features a wet armature design where the working fluid surrounds the armature, suitable for systems using phosphate ester fluids thanks to cartridges configured with EPDM seals. However, it is critical to avoid exposure to petroleum-based fluids to prevent seal damage. The interchangeable coils from Sun\u2019s Series 1 solenoid products add versatility and can be mounted in either direction on the tube. Moreover, the DMDAMNV236 incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue due to excessive installation torque or cavity/cartridge machining variations. With a capacity of 12 gpm (45 L/min) and a typical response time of 50 ms, this valve supports a maximum operating pressure of 5000 psi (350 bar) and can handle up to 15000 switching cycles per hour. Manual override options are available but are intended for temporary actuation with an expected mechanical life of approximately 7,000 cycles. This valve also features low leakage rates and requires minimal manual override force, making it efficient and easy to operate within various hydraulic setups. Its compact size (.60 lb or 0.30 kg) and robust construction ensure reliability and longevity in challenging industrial environments.

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.
