The Sun Hydraulics DNCALTN2E24V (DNCALTN2E24V) is a solenoid-operated, 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional design. This valve features a closed transition between positions to significantly reduce oil loss during shifting, making it particularly beneficial for pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank but does not guarantee performance for reverse flow. The solenoid tube assembly is rated for fatigue at up to 5000 psi (350 bar), and the valve requires no minimum hydraulic pressure for operation thanks to its direct actuation. The DNCALTN2E24V employs a wet armature design, with working fluid surrounding the armature, which can be exposed to coil-generated heat. This may affect fluid stability over time, especially in water-glycol mixtures that could form varnishes impacting function. The valve's solenoid boasts a unique magnetic design that enhances efficiency by providing high spool actuating force per watt of power used, ensuring reliable shifting. It is compatible with various coil termination and voltage options, some offering surge protection and weatherization up to IP69K ratings. The DNCALTN2E24V incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or cavity machining variations. It fits into a T-31A cavity and has an 8 gpm (30 L/min) capacity with a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 50 ms, with a switching frequency of up to 15,000 cycles per hour. Manual override requires minimal force and stroke for operation. The cartridge weighs .60 lb (0.30 kg) and uses Viton seals for compatibility with specific fluids while avoiding petroleum-based products that could damage EPDM seals.

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.
