The Sun Hydraulics DMDALBV223 (DMDALBV223) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. 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). It features spools B and R which are closed during the transition between positions, enhancing performance by providing faster and more consistent response times, particularly suitable for applications where capacity is not a critical factor. The DMDALBV223 incorporates a wet armature design allowing the working fluid to surround the armature, which is beneficial in reducing wear but requires consideration regarding fluid type due to potential heat generation during prolonged coil energization. Notably, cartridges with EPDM seals are specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model also offers versatility in manual control options with the availability of D or L controls, featuring a detent mechanism in the manual override for temporary actuation. The mechanical life expectancy of these manual control assemblies is about 7,000 cycles. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products add to its adaptability and ease of use. Engineered with Sun\u2019s floating style construction minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This construction detail ensures reliability and longevity of the valve even under stringent installation conditions. With its robust build and versatile features, the DMDALBV223 is an ideal choice for various hydraulic control applications requiring precise flow management and rapid response times.

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.
