The Sun Hydraulics DMDADPV524 (DMDADPV524) is a solenoid-operated 3-way, 2-position cartridge valve that exemplifies precision and durability in hydraulic system controls. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it exceptionally versatile for various applications. It features a fatigue rating for up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. The DMDADPV524 valve is particularly noted for its closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for pilot control applications where capacity is less critical. The manual override included in models with the D or L control is designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Additionally, the valve supports cartridges configured with EPDM seals suitable for systems using phosphate ester fluids. This model also benefits from a wet armature design where the working fluid surrounds the armature, which could be significant when the coil is energized over extended periods. The design helps manage the heat generated but requires consideration of fluid compatibility to prevent breakdown and varnish formation. Moreover, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The Sun Hydraulics' floating style construction incorporated into this valve minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), alongside rapid typical response times of 50 ms and switching frequency up to 15000 cycles/hr, this model ensures efficient operation and reliable performance in demanding hydraulic setups.

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.
