The Sun Hydraulics DNCATAV72419 (DNCATAV72419) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, significantly reducing oil loss during shifting\u2014an essential characteristic for pilot control circuits. With port 3 designated as the inlet and port 1 as the tank, it is optimized for specific flow directions; while reverse flow is possible, it may not perform optimally and is generally not recommended. The solenoid tube assembly is built to withstand pressures up to 5000 psi (350 bar), ensuring durability in demanding environments. This valve operates without the need for minimum hydraulic pressure and incorporates EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. The wet armature design exposes the armature to working fluid and heat from the coil, which could impact performance if energized continuously with certain fluids like water-glycol mixtures. The solenoid's magnetic design enhances efficiency by maximizing spool actuating force per watt of energy used, ensuring reliable operation. It offers flexibility with various coil termination and voltage options available, including surge protection features. Coils are interchangeable with other Sun Series 1 products and can be mounted bidirectionally on the tube. Connector options provide ratings up to IP69K for robust protection against environmental factors. Built using Sun's floating style construction, this valve minimizes risks of internal binding due to installation torque or machining variations in cavity/cartridge interfaces. It has a capacity of 8 gpm (30 L/min), a typical response time of 50 ms, and can handle a switching frequency of up to 15,000 cycles per hour with a manual override feature requiring minimal force.

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.
