The Sun Hydraulics DNCALBV724 (DNCALBV724) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. Designed as a direct-acting, balanced spool directional valve, it features a closed transition between positions to minimize the loss of oil during shifting. This attribute is especially beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The valve operates efficiently with port 3 as the inlet and port 1 as the tank, although it permits reverse flow under specific conditions. Engineered for robust performance, the DNCALBV724 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 8 gpm (30 L/min). Its solenoid tube assembly is fatigue rated for demanding applications and requires no minimum hydraulic pressure for operation. The design includes EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances. The valve's wet armature design allows the working fluid to surround the armature, which could be significant when considering thermal management during prolonged energization periods. A diverse range of coil termination and voltage options are available to suit various operational needs and environmental conditions. With a rapid response time typically around 50 ms and capable of up to 15,000 switching cycles per hour, this valve ensures reliable performance in dynamic systems. Additionally, its interchangeable coils with other Sun Series 1 solenoid products offer versatility in maintenance and replacement scenarios. Sun Hydraulics has also incorporated their floating style construction into the DNCALBV724 to reduce potential internal binding caused by installation torque or variations in cavity/cartridge machining \u2013 ensuring consistent operation and longevity of the valve system.

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.
