The Sun Hydraulics DMDATPV (DMDATPV) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. 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 DMDATPV model features a fatigue-rated solenoid tube assembly suitable for demanding applications. The valve operates efficiently without minimum hydraulic pressure, enhancing its versatility in various system configurations. It includes spools B and R, which are closed during the transition between positions, thus ensuring faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the valve allows the working fluid to surround the armature, which is beneficial for heat dissipation but requires consideration regarding fluid selection due to potential breakdowns at high temperatures. For maintenance or manual operation, the DMDATPV comes with a manual override feature that has a mechanical life expectancy of about 7,000 cycles. It also incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Overall, this robust valve integrates seamlessly with other Sun Series 1 solenoid products due to its interchangeable coils that can be mounted on the tube in either direction, adding to its flexibility and ease of use in complex hydraulic systems.

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.
