The Sun Hydraulics DMDAXPN636 (DMDAXPN636) 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 requires no minimum hydraulic pressure for operation, enhancing its reliability and performance across various applications. The valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding environments. The DMDAXPN636 utilizes a wet armature design where the working fluid surrounds the armature, which is crucial in maintaining the temperature and efficiency of the system during prolonged energization of the coil. It has interchangeable coils with other Sun Series 1 solenoid products, allowing for flexible installations and maintenance. This model also incorporates Sun's floating style construction to prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), the valve is equipped to handle substantial flow rates efficiently. It also features quick response times typically around 50 ms and maintains low leakage levels at high pressures, ensuring minimal loss and higher system efficiency. The manual override feature included in models equipped with D or L control offers temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Designed specifically for systems using phosphate ester fluids, this valve should not be exposed to petroleum-based fluids as they can damage the EPDM seals. Its versatility in manual and electrical operations makes it an essential component for various hydraulic applications requiring reliable performance and precise control.

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.
