The Sun Hydraulics DNCAMBN724N (DNCAMBN724N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve is particularly suitable for applications where minimizing oil loss during position transitions is critical, such as in pilot control circuits. The valve's capacity relies on port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance inconsistencies. It operates effectively without requiring a minimum hydraulic pressure and features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar). The valve accommodates EPDM seals for use in systems with phosphate ester fluids, avoiding exposure to petroleum-based substances that could cause seal damage. The DNCAMBN724N utilizes a wet armature design, allowing the working fluid to surround the armature, which can be affected by coil-generated heat over prolonged periods. This design consideration is especially relevant for fluids like water-glycol mixtures that may degrade into varnishes under high temperatures. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt expended, ensuring reliable valve operation. Additionally, it supports various coil termination and voltage options with or without surge protection, and its coils are interchangeable with other Sun Series 1 products. With a cavity size of T-31A and a series designation of 1, this valve has an operational capacity of up to 8 gpm (30 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar). It boasts a typical response time of 50 ms and can endure switching frequencies up to 15,000 cycles per hour. The manual override requires minimal force and stroke for operation. Designed with Sun's floating style construction, it minimizes internal part binding risks due to installation torque or machining variations.

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.
