The Sun Hydraulics DMDAXRV736 (DMDAXRV736) is a high-performance solenoid-operated 3-way, 2-position cartridge directional valve designed for robust hydraulic control applications. This direct-acting, balanced spool valve operates without the need for minimum hydraulic pressure, enhancing its versatility in various system configurations. The DMDAXRV736 features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times especially suitable for pilot control applications where capacity is less critical. Equipped with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, the valve ensures durability and reliability in demanding environments. It supports a maximum flow capacity of 12 gpm (45 L/min) and can handle switching frequencies up to 15,000 cycles per hour. The manual override option, available with D or L control models, includes a detent mechanism designed for temporary actuation with a mechanical life expectancy around 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based fluids. The wet armature design of the valve allows the working fluid to surround the armature which could be crucial when considering fluid types that degrade at higher temperatures due to prolonged coil energization. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Its interchangeable coils with other Sun Series 1 solenoid products add to its flexibility in assembly and maintenance processes. With these advanced features and robust construction, the Sun Hydraulics DMDAXRV736 valve is an excellent choice for sophisticated hydraulic systems requiring precise control and high 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.
