The Sun Hydraulics DMDATPN836 (DMDATPN836) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Its response time is exceptionally quick at approximately 50 ms, making it suitable for applications requiring fast actuation. The DMDATPN836 incorporates advanced features such as closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The construction of the DMDATPN836 includes a wet armature design, where the working fluid surrounds the armature. This setup aids in cooling but requires consideration of fluid type as certain fluids may degrade under prolonged exposure to heat. The valve\u2019s solenoid coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction for flexible installation options. Additionally, the valve employs Sun's floating style construction which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. This model also features manual override capabilities with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. It is important to note that cartridges configured with EPDM seals should only be used with phosphate ester fluids to prevent seal damage from petroleum-based fluids. With its robust design and versatile performance characteristics, the DMDATPN836 is well-suited for various hydraulic applications demanding reliability and precision.

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.
