The Sun Hydraulics DMDAMNVHN24AB (DMDAMNVHN24AB) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design that ensures reliable operation without the need for minimum hydraulic pressure. This valve is particularly suited for applications requiring precise control and fast response times, as it is fatigue rated for 5000 psi (350 bar) service and has a typical response time of 50 ms. The DMDAMNVHN24AB incorporates closed transitions between Spools B and R, which enhances performance by providing faster and more consistent responses ideal for pilot controls where capacity is less critical. For manual override situations, the valve includes a detent mechanism designed to support temporary actuation with an expected mechanical life of around 7,000 cycles. This model uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. It also features a wet armature design in which the working fluid surrounds the armature\u2014important to consider when dealing with long periods of coil energization. Interchangeability is a key aspect of this valve; its coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve also benefits from Sun's floating style construction which minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar) and capacity up to 12 gpm (45 L/min), this cartridge valve stands out for its robustness and versatility in various hydraulic control 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.
