The Sun Hydraulics DMDALNV736 (DMDALNV736) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is 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). The valve features closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. Notably, the DMDALNV736 requires no minimum hydraulic pressure to operate, making it versatile for various hydraulic circuits. It includes options for manual override controls (D, L, T) with a mechanical life expectancy of around 7,000 cycles. The valve\u2019s design incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. Another key aspect of the DMDALNV736 is its wet armature design where the working fluid surrounds the armature. This setup helps in heat management but requires consideration regarding fluid selection as some may degrade under prolonged exposure to heat. Furthermore, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction uses Sun's floating style to minimize internal parts binding due to installation torque or machining variations of cavity/cartridge. This feature ensures reliability and longevity in demanding applications. The product dimensions include a solenoid tube diameter of .75 inches (19 mm) and an installation torque requirement between 30 - 35 lbf.ft (41 - 47 Nm). Overall, the Sun Hydraulics DMDALNV736 offers robust performance for sophisticated hydraulic systems requiring precise control and durability.

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.
