The Sun Hydraulics DMDAMPN72499 (DMDAMPN72499) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is built to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for the same, ensuring durability and reliability in demanding applications. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. The DMDAMPN72499 operates without requiring a minimum hydraulic pressure, facilitating its use in various system configurations. It incorporates manual override options with detent mechanisms designed for temporary actuation, supporting mechanical life expectancies of around 7,000 cycles. For environments using phosphate ester fluids, cartridges with EPDM seals are recommended to avoid damage from petroleum-based substances. Additionally, the design includes a wet armature setup where the working fluid surrounds the armature which may be exposed to heat if the coil remains energized for extended periods. This factor needs consideration especially with fluids like water-glycol mixtures that can degrade under heat. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easier maintenance and replacement processes. The construction also features Sun\u2019s floating style which minimizes internal parts binding that could occur due to excessive installation torque or cavity/cartridge machining variations. This model has a flow capacity of up to 12 gpm (45 L/min), typical response time of 50 ms, and can handle switching frequencies up to 15,000 cycles/hr. It is designed with user-friendly dimensions including a solenoid tube diameter of .75 inches (19 mm) and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). Weighing just .60 lb (0.30 kg), it offers a compact yet robust solution for directional control in hydraulic systems.

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.
