The Sun Hydraulics DNCATAN72499 (DNCATAN72499) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This valve is engineered with a closed transition between positions to significantly minimize oil loss during shifting, which is crucial for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance issues. It operates effectively under high pressure, being fatigue rated for up to 5000 psi (350 bar), and does not require a minimum hydraulic pressure for actuation. The valve utilizes EPDM seals compatible with phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. Its wet armature design allows the working fluid to surround the armature, but care must be taken with fluid selection as certain mixtures may degrade under prolonged coil energization. The solenoid's magnetic design ensures high efficiency with substantial spool actuating force per watt expended, promoting reliable operation. A variety of coil termination and voltage options are available, including models with surge protection. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. Options for coil connectors are rated up to IP69K for enhanced environmental protection. The floating style construction minimizes internal binding risks due to installation torque or machining variations. This cartridge fits into cavity T-31A and supports a flow capacity of 8 gpm (30 L/min). It has a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles per hour. The valve's manual override requires minimal force for operation and features a stroke of .10 inches (2.5 mm). Installation torque ranges from 30-35 lbf ft (41-47 Nm), ensuring secure placement without compromising functionality.

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.
