The Sun Hydraulics DMDAMNV612 (DMDAMNV612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation in various hydraulic systems. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it is suitable for demanding applications requiring precise control. The valve features interchangeable coils from the Sun Series 1 solenoid products, which can be mounted in either direction on the tube, enhancing its versatility. The wet armature design ensures that the working fluid surrounds the armature, which is crucial for maintaining temperature and performance during prolonged energization. However, this may affect fluid integrity over time, especially with water-glycol mixtures. Equipped with EPDM seals, the DMDAMNV612 is specifically configured for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Its manual override mechanism is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The construction incorporates Sun\u2019s floating style to minimize internal parts binding due to excessive installation torque or cavity-cartridge machining variations. This feature contributes significantly to the reliability and longevity of the valve under varied operational conditions. With its quick response time of typically 50 ms and minimal maximum valve leakage at high pressures (5 in\u00b3/min at 3000 psi), this model meets stringent performance criteria for industrial hydraulic systems. Additionally, it supports a high switching frequency up to 15,000 cycles/hr, making it ideal for applications requiring frequent operation transitions without compromise on performance stability.

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.
