The Sun Hydraulics DMDADNV636 (DMDADNV636) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a fatigue rating for up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The DMDADNV636 is particularly noted for its closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times during the shift from one position to another. This model operates without requiring a minimum hydraulic pressure, which allows for flexibility in various system conditions. It also includes optional manual override controls (D, L, T) with a mechanical life expectancy of around 7,000 cycles. The manual override is designed primarily for temporary actuation rather than continuous use. The valve's wet armature design means the working fluid surrounds the armature; this design consideration is crucial as it affects temperature management when the coil is continuously energized. Suitable fluids include phosphate ester types, as models with EPDM seals should not be exposed to petroleum-based substances to avoid damage. Additionally, the DMDADNV636 can handle up to 12 gpm (45 L/min) and features interchangeable coils compatible with other Sun Series 1 solenoid products. This versatility is complemented by its floating style construction which minimizes internal part binding due to installation variances or machining discrepancies. With a quick typical response time of 50 ms and maximum operating pressure maintenance at 5000 psi (350 bar), this valve ensures reliability and precision in controlling fluid direction in hydraulic circuits.

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.
