The Sun Hydraulics DMDAMRV71219 (DMDAMRV71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design that is optimal for applications requiring precise control and reliability. The valve operates with no minimum hydraulic pressure needed, enhancing its versatility in various hydraulic systems. Designed for durability, the solenoid tube assembly is fatigue rated for service at pressures up to 5000 psi (350 bar). This model incorporates a closed transition between Spools B and R, which enhances performance by providing faster and more consistent response times when used as pilot controls. This design characteristic makes it particularly suitable for applications where rapid actuation and high cycling frequency are critical. The valve also includes manual override options with detent mechanisms designed for temporary actuation, supporting approximately 7,000 cycles. Equipped with EPDM seals, the DMDAMRV71219 is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. It features a wet armature design where the working fluid surrounds the armature which could be relevant in scenarios where the coil remains energized over extended periods. Additional technical specifications include a flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, maximum leakage at 3000 psi rated at 5 in\u00b3/min., and a switching frequency capability of up to 15,000 cycles per hour. The cartridge also supports interchangeable coils from other Sun Series 1 solenoid products and can be mounted on the tube in either direction to accommodate different installation requirements. This model's robust construction minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations, ensuring reliable operation and longevity in demanding environments.

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.
