The Sun Hydraulics DMDADBV814N (DMDADBV814N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The valve features a unique closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times when used as pilot controls. Constructed with durability in mind, the solenoid tube assembly of the DMDADBV814N is fatigue rated for service at pressures up to 5000 psi (350 bar). It incorporates Sun Hydraulics' floating style construction which minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining. This model is particularly suitable for applications where high switching frequency and quick response times are critical, supporting up to 15,000 cycles per hour with a typical response time of 50 ms. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids. The manual override feature in models equipped with D or L control is designed for temporary actuation only, with a mechanical life expectancy of approximately 7,000 cycles. Additionally, the wet armature design means that the working fluid surrounds the armature which can be a consideration if the coil remains energized for extended periods. This model also boasts interchangeable coils with other Sun Series 1 solenoid products and can handle flow capacities up to 12 gpm (45 L/min), making it an adaptable solution for diverse hydraulic system requirements.

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.
