The Sun Hydraulics DMDALPV297 (DMDALPV297) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it highly effective in a variety of applications. It features the Sun floating style construction that prevents internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Engineered for durability and reliability, the DMDALPV297 valve has a fatigue rating of 5000 psi (350 bar) and incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial for applications where the coil may be energized for extended periods, potentially affecting fluid integrity over time. The solenoid tube assembly ensures rapid and consistent response times with typical response times clocked at 50 ms. The valve offers interchangeable coils with other Sun Series 1 solenoid products and can be mounted on the tube in either direction for enhanced versatility. Designed with EPDM seals specifically for use with phosphate ester fluids, it is essential to avoid exposure to petroleum-based fluids which could damage these seals. The manual override feature is equipped with a detent mechanism intended for temporary actuation only. With a maximum operating pressure of 5000 psi (350 bar) and flow capacity up to 12 gpm (45 L/min), this valve ensures minimal leakage at high pressures\u20145 in\u00b3/min at 3000 psi\u2014and supports switching frequencies up to 15000 cycles/hr. Its robust construction and thoughtful design make it suitable for demanding environments where precision and reliability are paramount.

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.
