The Sun Hydraulics DMDADPV71219 (DMDADPV71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional mechanism designed to operate seamlessly under a maximum pressure of 5000 psi (350 bar). With a typical response time of 50 ms and capable of handling up to 12 gpm (45 L/min), this valve ensures efficient flow control in various hydraulic systems. The DMDADPV71219 incorporates advanced design features such as closed transitions between spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. Its wet armature design allows the working fluid to surround the armature, optimizing heat management but requiring attention to fluid type as certain fluids may degrade under prolonged exposure to heat. This model is compatible with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based products which can cause damage. The manual override feature equipped with detent mechanisms (D or L control) supports temporary actuation with a mechanical life expectancy of around 7,000 cycles. Interchangeability with other Sun Series 1 solenoid products adds versatility in terms of coil replacements and mounting orientations. Furthermore, the valve's construction minimizes internal part binding risks due to its floating style design which accommodates installation torque and machining variations effectively. This robust construction and thoughtful engineering make the Sun Hydraulics DMDADPV71219 an essential component for reliable hydraulic system operations across various applications.

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.
