The Sun Hydraulics DMDAMPV636 (DMDAMPV636) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve offers precision control with its closed transition between positions B and R, enhancing performance by reducing capacity for faster and more consistent response times. Ideal for applications requiring no minimum hydraulic pressure for operation, the DMDAMPV636 excels in environments where rapid directional changes are essential. The unit features a wet armature design where the working fluid surrounds the armature, which can be critical when the coil is energized over long periods due to potential breakdown of certain fluids like water-glycol mixtures. It is compatible with EPDM seals specifically suited to phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. The valve's manual override mechanism is designed primarily for temporary actuation and boasts a mechanical life expectancy of around 7,000 cycles. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), this cartridge valve maintains robust performance under demanding conditions. It also features interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to reduce internal part binding due to installation variances. This model's quick response time of approximately 50 ms and its ability to handle switching frequencies up to 15,000 cycles per hour make it an adaptable choice for various high-demand hydraulic applications.

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.
