The Sun Hydraulics DNCAMJV948 (DNCAMJV948) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically designed with a closed transition between positions to minimize oil loss during shifting, making it ideal for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance issues. It operates efficiently at a maximum pressure of 5000 psi (350 bar) without requiring any minimum hydraulic pressure for activation. The DNCAMJV948 incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals should not be exposed to petroleum-based fluids to avoid damage. The valve's wet armature design allows the working fluid to cool the armature but requires consideration of fluid breakdown over time when exposed to prolonged coil heat. The solenoid offers high efficiency with significant actuating force per watt, ensuring reliable operation and compatibility with other Sun Series 1 solenoid products. Various coil termination and voltage options are available, including weatherized coils for enhanced environmental protection and IP69K-rated connectors. The floating style construction helps prevent internal binding due to installation torque or machining variations in the cavity or cartridge. With a capacity of up to 8 gpm (30 L/min), a typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour, this valve is robust and reliable for demanding applications. It also features manual override capabilities with specific force requirements and stroke measurements, ensuring flexible operation when needed.

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.
