The Sun Hydraulics DNCALZV248 (DNCALZV248) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, significantly minimizing oil loss during shifting, which is particularly beneficial in pilot control circuits. It is optimized for use with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance degradation. The solenoid tube assembly of this valve is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring robust performance under demanding conditions. This valve operates without requiring minimum hydraulic pressure and features a wet armature design that allows the working fluid to surround the armature. This design can be advantageous or disadvantageous depending on the fluid type and operating conditions; for example, water-glycol mixtures may degrade over time when exposed to heat generated by the coil. The DNCALZV248 offers flexibility with a wide range of coil termination and voltage options available, including configurations with surge protection. Additionally, this model incorporates Sun's floating style construction, reducing the risk of internal binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. The valve supports a capacity of 8 gpm (30 L/min) and has a response time of approximately 50 ms. It also boasts an impressive switching frequency capability of up to 15,000 cycles per hour. For manual operation, it requires an override force of about 5 lbs per 1000 psi at Port 1. Seal kits are available in Viton material for both cartridge and coil applications to ensure compatibility with various fluid types and environmental 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.
