The Sun Hydraulics DMDATAV836 (DMDATAV836) 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 characterized by its robust construction and capability to handle a maximum operating pressure of 5000 psi (350 bar). It features a fatigue-rated solenoid tube assembly suitable for demanding applications. The valve ensures closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDATAV836 operates without requiring a minimum hydraulic pressure, which facilitates its use in various hydraulic circuits. Models equipped with D or L control options include a manual override detent mechanism designed for temporary actuation, with an expected mechanical life of approximately 7,000 cycles. The valve is also available with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. This model incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil could lead to fluid degradation if not properly managed. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility and ease of maintenance. Additionally, the valve benefits from Sun's floating style construction which minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 3000 psi being limited to 5 in\u00b3/min. The compact and efficient design of the DMDATAV836 makes it an essential component for advanced hydraulic systems requiring reliable directional control and rapid switching capabilities (up to 15,000 cycles/hr).

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.
