The Sun Hydraulics DNCALCV248 (DNCALCV248) is a high-performance, solenoid-operated 4-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition shifting. This design significantly minimizes oil loss during position transitions, which is particularly beneficial in pilot control circuits. The valve is designed to function optimally with port 3 as the inlet and port 1 as the tank outlet, and it includes a manual override feature with specific force and stroke requirements for emergency operation. This model is fatigue rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. It does not require a minimum hydraulic pressure to operate, making it versatile for various applications. The DNCALCV248 uses EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. A key feature of this valve is its wet armature design where the working fluid surrounds the armature. This can be critical if the coil remains energized for extended periods as some fluids may degrade at higher temperatures. The valve supports a variety of coil termination and voltage options, including models with surge protection. Furthermore, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The DNCALCV248 incorporates Sun Hydraulics' floating style construction which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It offers an operational capacity of 8 gpm (30 L/min) and features rapid response times typical at around 50 ms. The model also supports a high switching frequency of up to 15000 cycles per hour and maintains robust performance even under demanding 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.
