The Sun Hydraulics DNCATBV948 (DNCATBV948) 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, which significantly reduces oil loss during shifting\u2014a critical advantage in pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank; however, while reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), and the valve requires no minimum hydraulic pressure for operation. It incorporates EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based substances. The wet armature design allows the working fluid to surround the armature, which may affect functionality if the coil remains energized for extended periods. Notably, water-glycol mixtures may degrade over time under such conditions. This high-efficiency solenoid delivers substantial spool actuating force per watt expended, ensuring reliable valve shifting. The cartridges are compatible with various coil termination and voltage options, providing flexibility in application. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction on the tube. Connector options offer protection ratings up to IP69K for enhanced environmental resistance, with additional weatherized coils available. The DNCATBV948 features Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge configurations. With a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve supports applications requiring rapid response times of approximately 50 ms and can endure switching frequencies up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs/1000 psi at Port 1 and offers a stroke of .10 inches (2.5 mm).

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.
