The Sun Hydraulics DNCADZV748 (DNCADZV748) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial advantage in pilot control circuits. The valve is designed with port 3 as the inlet and port 1 as the tank outlet, supporting a flow capacity of 8 gpm (30 L/min) and accommodating a maximum operating pressure of 5000 psi (350 bar). The DNCADZV748 is engineered for robust performance with its solenoid tube assembly being fatigue rated for high-pressure service. It operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The use of EPDM seals in certain configurations makes it suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. This model employs a wet armature design where the working fluid surrounds the armature, thus exposed to heat from the coil which could affect fluid integrity over prolonged periods. Its magnetic design ensures high efficiency and effective spool actuating force per watt expended, providing reliable valve operation. The coils are interchangeable with other Sun Series 1 solenoid products and feature various connector options rated up to IP69K for enhanced environmental protection. Additionally, the DNCADZV748 incorporates Sun's floating style construction that minimizes internal part binding due to installation torque or machining variations in cavity/cartridge assemblies. This model also offers rapid response times typically around 50 ms and supports switching frequencies up to 15000 cycles per hour. With manual override capabilities and a variety of coil termination and voltage options available, this valve is adaptable for diverse hydraulic system requirements while ensuring dependable performance in demanding applications.

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.
