The Sun Hydraulics DMDADNV548 (DMDADNV548) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is particularly noted for its robust construction with the solenoid tube assembly being fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The valve operates with no minimum hydraulic pressure required, enhancing its versatility in various system configurations. The DMDADNV548 is equipped with EPDM seals specifically designed for use with phosphate ester fluids, ensuring durability and resistance against petroleum-based fluids which can damage the seals. Its wet armature design allows the working fluid to surround the armature, aiding in cooling but requiring consideration of fluid type to avoid breakdown and varnish formation that could impede functionality. This model also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Additionally, it offers quick and consistent response times courtesy of closed transitions between spool positions B and R. The manual override feature found in models equipped with D or L control is intended for temporary actuation and supports a mechanical life expectancy of approximately 7,000 cycles. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), the DMDADNV548 suits a wide range of hydraulic control applications. It also features interchangeable coils with other Sun Series 1 solenoid products for enhanced flexibility in system design. This valve's design ensures reliable performance even under high switching frequencies up to 15,000 cycles per hour, making it an ideal choice for systems requiring frequent operation transitions.

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.
