The Sun Hydraulics DMDAMBV928 (DMDAMBV928) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust applications, featuring a fatigue rating for 5000 psi (350 bar) service. It is particularly noted for its closed transitions between Spools B and R, enhancing performance limits while reducing capacity, making it ideal for pilot control applications where consistent and fast response times are critical. This versatile valve requires no minimum hydraulic pressure to operate and includes options for manual overrides with detent mechanisms intended for temporary actuation. The manual control assembly boasts a mechanical life expectancy of about 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. The DMDAMBV928 utilizes a wet armature design allowing the working fluid to surround the armature which helps in managing the heat generated by the coil. However, it's important to note that prolonged energization of the coil can lead to breakdowns in certain fluids like water-glycol mixtures. The valve\u2019s design incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction which reduces risks of internal parts binding due to installation errors or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 5 in\u00b3/min at 3000 psi. It supports switching frequencies up to 15,000 cycles per hour and has manual override requirements detailed as needing a force of about 5 lbs at 1000 psi on Port 1. The compact design measures a valve hex size of 7/8 in (22.2 mm) and weighs approximately 0.60 lb (0.30 kg).

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.
