The Sun Hydraulics DMDAMPV914 (DMDAMPV914) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features a unique closed transition between positions B and R, optimizing performance by providing faster and more consistent response times particularly when used as pilot controls where capacity is less critical. This model is fatigue rated for demanding applications and incorporates a wet armature design, where the working fluid surrounds the armature. This setup helps in efficient heat dissipation but requires consideration of fluid characteristics as certain fluids may degrade at higher temperatures. The DMDAMPV914 is compatible with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids which can cause damage. Additionally, the manual override feature on this model includes a detent mechanism designed for temporary actuation with an expected mechanical life of about 7,000 cycles. Coils used in the DMDAMPV914 are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction for added flexibility. The construction of the valve utilizes Sun\u2019s floating style design to minimize internal parts binding due to installation torque or variations in cavity/cartridge machining. This valve's robust construction and versatile design make it suitable for various hydraulic applications requiring reliable 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.
