The Sun Hydraulics DMDAXPV912N (DMDAXPV912N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed with a fatigue rating for 5000 psi (350 bar) service, making it suitable for rigorous industrial applications. The valve features closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times during operation. This characteristic is particularly beneficial in pilot control applications where capacity is less critical. The DMDAXPV912N operates without requiring a minimum hydraulic pressure, providing flexibility in various operating conditions. It includes manual override options with a detent mechanism designed for temporary actuation, and the mechanical life expectancy of these controls is around 7,000 cycles. Specifically configured cartridges with EPDM seals are intended for use with phosphate ester fluids; however, they are not compatible with petroleum-based fluids as these could damage the seals. This model incorporates Sun Hydraulics' wet armature design allowing the working fluid to surround the armature which may affect fluid integrity under prolonged energization. The interchangeable coils compatible with other Series 1 solenoid products offer versatility in maintenance and replacement procedures. Additionally, the floating style construction minimizes internal parts binding, which can occur due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and a maximum operating pressure of 5000 psi (350 bar). The valve also supports a high switching frequency up to 15000 cycles/hr and has been designed to ensure ease of installation and long-term reliability in demanding environments.

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.
