The Sun Hydraulics DNCALCN736 (DNCALCN736) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. It features a direct-acting, balanced spool with closed transition between positions, minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. The valve is configured to use port 3 as the inlet and port 1 as the tank, supporting a flow capacity of up to 8 gpm (30 L/min) and operating pressures up to 5000 psi (350 bar). Designed for durability and reliability, the DNCALCN736's solenoid tube assembly is fatigue rated for demanding applications. It operates without requiring a minimum hydraulic pressure, making it versatile across various hydraulic systems. The valve\u2019s EPDM seals are specifically chosen for compatibility with phosphate ester fluids, though they must not be exposed to petroleum-based substances which could cause damage. This model incorporates Sun Hydraulics' wet armature design wherein the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods as it can affect fluid integrity in some cases. Moreover, the DNCALCN736 offers a variety of coil termination and voltage options to suit different operational needs and environments. The solenoid\u2019s magnetic design enhances efficiency by maximizing spool actuating force per Watt expended, ensuring reliable valve shifting even under challenging conditions. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environmental resilience, options include weatherized coils and kits rated up to IP69K. Finally, Sun Hydraulics' floating style construction in this model reduces risks associated with internal parts binding due to installation torque or cavity/cartridge machining variations\u2014further enhancing its robustness and reliability in field operations.

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.
