The Sun Hydraulics DMDALAN924 (DMDALAN924) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min). The DMDALAN924 is notable for its closed spool positions during transitions, which enhances performance by providing faster and more consistent response times, making it ideal for applications requiring precise control such as pilot operations where capacity is less critical. This valve operates without the need for minimum hydraulic pressure and incorporates a wet armature design. The surrounding working fluid in this design helps manage the heat generated by the coil but requires careful consideration of fluid selection to prevent breakdown and varnish formation that could impair valve function. It's equipped with EPDM seals suitable for phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility, allowing for easy maintenance and replacement. The manual override feature in models with D or L control is designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. Additionally, Sun's floating style construction minimizes internal parts binding caused by installation torque or machining variations. Overall, the Sun Hydraulics DMDALAN924 valve offers robust construction and reliable performance suitable for demanding hydraulic applications requiring precise directional control and rapid response times.

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.
