The Sun Hydraulics DNCALSV71219 (DNCALSV71219) is a solenoid-operated, 4-way, 2-position cartridge valve specifically designed for direct-acting and balanced spool directional control. This valve is notable for its closed transition between positions, which significantly minimizes oil loss during shifting\u2014a feature especially beneficial in pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank, although reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly of this valve is fatigue-rated for service up to a maximum operating pressure of 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. This valve does not require any minimum hydraulic pressure for operation, making it versatile across various applications. Its wet armature design allows the working fluid to surround the armature, which can be crucial when considering heat dissipation from the coil during prolonged energization periods. Users should note that certain fluids like water-glycol mixtures may degrade over time at high temperatures, affecting functionality. The DNCALSV71219 offers a range of coil termination and voltage options with or without surge protection, enhancing its adaptability to different operational environments. The solenoid's unique magnetic design delivers high efficiency by providing substantial spool actuating force per watt expended, contributing to consistent and reliable valve shifting. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With a capacity of 8 gpm (30 L/min) and a typical response time of 50 ms, this valve supports high-frequency switching up to 15,000 cycles per hour. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces.

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.
