The Sun Hydraulics DMDADRV924 (DMDADRV924) 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 well-suited for applications requiring robust performance as it features a fatigue rating of 5000 psi (350 bar). The valve ensures smooth transitions with its spools B and R closed in the transition between positions, enhancing the response time and consistency which is critical in pilot control applications. The DMDADRV924 operates efficiently without minimum hydraulic pressure, featuring various manual controls including D, L, and T types which offer a mechanical life expectancy of approximately 7,000 cycles. Its design incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The valve's wet armature design allows the working fluid to surround the armature which helps manage heat during prolonged energization but requires careful consideration of fluid characteristics to prevent breakdown and varnish formation. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing mounting on the tube in either direction. The construction minimizes internal parts binding by adopting Sun\u2019s floating style construction which accounts for excessive installation torque and/or cavity-cartridge machining variations. With a switching frequency capable of reaching up to 15,000 cycles per hour and a quick typical response time of 50 ms, the DMDADRV924 is an excellent choice for demanding applications where reliability and precision 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.
