The Sun Hydraulics DMDAMNN936 (DMDAMNN936) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional control mechanism. This unit is designed to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for demanding applications. With its closed spool transitions between positions B and R, the valve ensures higher performance at the cost of lower capacity, making it ideal for pilot control applications where quick and consistent response times are critical. The DMDAMNN936 operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. It includes manual override options with detent mechanisms (models with D or L control), which are intended for temporary actuation; these models have an expected mechanical life of around 7,000 cycles. The valve\u2019s compatibility with EPDM seals makes it suitable for systems using phosphate ester fluids, though these seals must not be exposed to petroleum-based substances. A notable feature of this model is its wet armature design, wherein the working fluid surrounds the armature that may be susceptible to heat during prolonged coil energization\u2014important to consider in applications involving heat-sensitive fluids. Additionally, the interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. Further enhancing its reliability and ease of installation, the DMDAMNN936 incorporates Sun\u2019s floating style construction to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve is an efficient solution for advanced hydraulic systems requiring robust control and swift actuation.

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.
