The Sun Hydraulics DMDATNV636 (DMDATNV636) is a high-performance solenoid-operated 3-way, 2-position cartridge valve engineered for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is designed to operate without minimum hydraulic pressure, enhancing its responsiveness and reliability across various applications. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it meets the demands of rigorous industrial environments. The DMDATNV636 features closed transitions between positions B and R, optimizing performance by ensuring faster and more consistent response times, especially suitable for pilot control applications where high capacity is not critical. Its robust construction includes a fatigue-rated solenoid tube assembly and interchangeable coils compatible with other Sun Series 1 solenoid products, allowing for flexible installation options. This model incorporates Sun\u2019s floating style construction to minimize internal parts binding, which can occur due to excessive installation torque or variations in cavity/cartridge machining. The manual override feature is equipped with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy up to approximately 7,000 cycles. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature; this needs consideration regarding fluid selection as some fluids may degrade under prolonged exposure to heat. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended since exposure to petroleum-based fluids can damage these seals. The DMDATNV636 also offers practical maintenance features such as easy-access seal kits for both cartridge and coil components ensuring long-term durability and ease of service.

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.
