The Sun Hydraulics DMDAMBV612 (DMDAMBV612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve is particularly suited for applications requiring precise control with a fast response time, boasting typical response times of 50 ms. It operates without the need for minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. Featuring a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDAMBV612 is engineered to handle demanding conditions while ensuring minimal internal leakage at high pressures\u2014up to 5 in\u00b3/min at 3000 psi. The valve's construction includes EPDM seals suitable for phosphate ester fluids, although these seals must be protected from exposure to petroleum-based fluids which can cause damage. The DMDAMBV612 utilizes a wet armature design where the working fluid surrounds the armature, helping manage heat dissipation during prolonged energization periods. This design feature is critical in maintaining fluid integrity and preventing breakdowns that could affect performance. Additionally, the valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction for increased installation flexibility. This model also incorporates Sun\u2019s floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With its durable design and comprehensive features, the DMDAMBV612 offers reliable performance and adaptability for sophisticated hydraulic systems requiring precise directional control and rapid switching capabilities.

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.
