The Sun Hydraulics DMDATPN548 (DMDATPN548) is a solenoid-operated 3-way, 2-position cartridge valve engineered for high-performance hydraulic systems. This direct-acting, balanced spool directional valve offers precise control with its robust design featuring a fatigue rating for service up to 5000 psi (350 bar). The DMDATPN548 is particularly effective in applications requiring reliable switching and control of hydraulic flow with minimal leakage, supporting a maximum operating pressure of 5000 psi and a flow capacity of 12 gpm (45 L/min). This model is distinguished by its closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve's wet armature design allows the working fluid to cool the armature, suitable for long energization periods, although care must be taken with fluid selection to prevent breakdown and varnish formation. For manual override operations, the DMDATPN548 includes a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. It utilizes EPDM seals configured specifically for phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, this model features interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to minimize internal part binding due to installation stresses or cavity/cartridge machining discrepancies. With its comprehensive capabilities and robust construction, the DMDATPN548 is an excellent choice for sophisticated hydraulic systems demanding high reliability and performance.

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.
