The Sun Hydraulics DMDALAN636 (DMDALAN636) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding environments. The valve operates with no minimum hydraulic pressure required, ensuring reliable performance under diverse conditions. The DMDALAN636 incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable when used as pilot controls where capacity is less critical. The wet armature design of the valve ensures that the working fluid surrounds the armature, which is crucial when the coil is energized for extended periods as it can affect fluid integrity over time. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. The manual override feature included in models with D or L control is designed for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. This valve also benefits from the interchangeability of coils with other Sun Series 1 solenoid products and features Sun's floating style construction to minimize internal parts binding. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDALAN636 offers versatility in installation and application. This model ensures minimal leakage and optimal response times typical at around 50 ms, making it an efficient choice for various hydraulic systems requiring precise control and reliability.

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.
