The Sun Hydraulics DNCALCV72499 (DNCALCV72499) is a high-performance, solenoid-operated directional valve, designed for efficient control in hydraulic systems. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with closed transitions that minimize oil loss during shifting, crucial for maintaining the integrity of pilot control circuits. Its configuration allows port 3 to act as the inlet and port 1 as the tank, supporting a flow capacity of up to 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar). The DNCALCV72499 is engineered with a fatigue-rated solenoid tube assembly suitable for up to 5000 psi service and does not require any minimum hydraulic pressure for operation. The valve\u2019s wet armature design ensures that the working fluid surrounds the armature, which is beneficial in prolonged coil energization scenarios but requires careful consideration of fluid type due to potential breakdown at high temperatures. This model offers versatility through various coil termination and voltage options, including configurations with surge protection. It features interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options are available up to IP69K for enhanced environmental protection. Sun Hydraulics has incorporated their floating style construction into this model to reduce the risk of internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The DNCALCV72499 also boasts rapid response times (typical 50 ms), low maximum valve leakage at high pressures (10 in\u00b3/min at 3000 psi), and supports a high switching frequency of up to 15,000 cycles per hour. This robust construction and thoughtful design make it an excellent choice for demanding applications requiring precise fluid control.

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.
