The Sun Hydraulics DNCATCV712 (DNCATCV712) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precision control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a critical aspect for pilot control circuits. The valve's capacity is optimized 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 degradation. The solenoid tube assembly of this valve is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This valve operates without the need for minimum hydraulic pressure due to its direct actuation design. It accommodates EPDM seals suitable for systems using phosphate ester fluids but requires caution as exposure to petroleum-based fluids can damage these seals. The wet armature design allows the working fluid to cool the armature but may lead to fluid breakdown at high temperatures if energized continuously. A variety of coil termination and voltage options are available, some offering surge protection and IP69K ratings for enhanced environmental resistance. The DNCATCV712's solenoid features a unique magnetic design that provides high efficiency and reliable spool actuation with minimal power consumption. Interchangeable coils with other Sun Series 1 solenoid products enhance versatility, permitting bidirectional mounting on the tube. Additionally, this model incorporates Sun's floating style construction to reduce binding risks from excessive installation torque or machining variations in cavities/cartridges. With a maximum flow capacity of 8 gpm (30 L/min), response time of approximately 50 ms, and switching frequency capability of up to 15,000 cycles per hour, this robust valve meets demanding operational requirements in hydraulic systems.

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.
