The Sun Hydraulics DMDATPV628 (DMDATPV628) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is engineered for precision and reliability in hydraulic systems. It features a fatigue-rated solenoid tube assembly designed to handle pressures up to 5000 psi (350 bar), making it suitable for rigorous applications. The DMDATPV628 valve ensures minimal leakage with maximum operating pressure sustainability, supporting up to 12 gpm (45 L/min) flow capacity. This model is particularly noted for its closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times during pilot control operations. The manual override options available with the D or L control include a detent mechanism designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. Users should note that EPDM seals in this cartridge are specifically intended for systems using phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The wet armature design of the valve allows the working fluid to surround the armature which might be susceptible to heat during prolonged energization\u2014this could impact fluid integrity over time. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in mounting orientations. Sun Hydraulics has incorporated their floating style construction into this model to minimize potential internal part binding caused by excessive installation torque or cavity/cartridge machining variations. This design feature helps ensure reliable operation and longevity of the component within hydraulic circuits.

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.
