The Sun Hydraulics DMDADBV836 (DMDADBV836) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is capable of handling a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Its robust construction includes a fatigue-rated solenoid tube assembly and interchangeable coils that are compatible with other Sun Series 1 solenoid products. The DMDADBV836 features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various system conditions. Additionally, the manual override option equipped with D or L control includes a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as they can degrade the seals. The wet armature design allows the working fluid to surround the armature which helps manage heat during prolonged coil energization but requires careful consideration of fluid type to avoid breakdown and varnish formation. Installation features include Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations. This model also supports quick response times typically around 50 ms and has a switching frequency capability up to 15,000 cycles per hour. The manual override requires minimal force and offers precise control through its stroke length. With its compact size and weight (.60 lb/0.30 kg), the DMDADBV836 provides an efficient solution for advanced hydraulic system applications requiring reliable directional control.

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.
