The Sun Hydraulics DNCADAN636 (DNCADAN636) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is characterized by its closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. Engineered to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 8 gpm (30 L/min), it ensures robust performance under demanding conditions. The DNCADAN636 operates without the need for minimum hydraulic pressure, allowing for versatile implementation in various hydraulic systems. It features EPDM seals configured specifically for use with phosphate ester fluids; however, these seals must not come into contact with petroleum-based fluids as they can cause damage. Its wet armature design means the working fluid surrounds the armature which is exposed to heat generated by the coil\u2014important to consider when using fluids like water-glycol mixtures that may degrade under prolonged exposure to high temperatures. This model also boasts a unique magnetic design that enhances solenoid efficiency, providing high spool actuating force per watt expended and ensuring reliable valve shifting. The solenoid tube assembly of this valve is fatigue rated for consistent performance even under extreme use. For added flexibility in application and installation, the coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Various coil connector options are available that offer up to IP69K protection rating. Furthermore, the DNCADAN636 incorporates Sun\u2019s floating style construction which minimizes potential internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature aids in maintaining operational reliability and longevity of the valve system.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- 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.
