The Sun Hydraulics DNCADTV297 (DNCADTV297) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. The DNCADTV297 operates without the need for minimum hydraulic pressure, enhancing its utility in a variety of applications. With an inlet at port 3 and an outlet at port 1, the valve supports a maximum flow capacity of 8 gpm (30 L/min) and can handle pressures up to 5000 psi (350 bar). It incorporates a fatigue-rated solenoid tube assembly suitable for up to 350 bar service, ensuring durability and reliability under high-pressure conditions. The valve's response time is typically swift at around 50 ms, with maximum leakage maintained at 10 in\u00b3/min at 3000 psi. This model uses EPDM seals when configured for systems with phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. The wet armature design of the solenoid means that the working fluid surrounds the armature which could lead to fluid degradation if the coil remains energized for extended periods. For versatility in installation and operation, the DNCADTV297 offers various coil termination and voltage options\u2014including models with surge protection\u2014and features interchangeable coils compatible with other Sun Series 1 solenoid products. Its robust construction includes Sun's floating style design which reduces risks of internal parts binding due to installation torque or cavity/cartridge machining variations. This model is also equipped with environmental protections through optional weatherized coils and kits, ensuring performance across diverse operating conditions.

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.
