The Sun Hydraulics DNCALWN914N (DNCALWN914N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve features a closed transition between positions, which significantly reduces oil loss during shifting, making it particularly advantageous in pilot control circuits. The valve is optimized with port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended due to performance limitations. It operates efficiently under fatigue-rated conditions up to 5000 psi (350 bar) without requiring minimum hydraulic pressure for activation. The valve's design incorporates a wet armature, allowing the working fluid to surround the armature and absorb heat from the coil; however, fluids like water-glycol mixtures may degrade over time at high temperatures. The DNCALWN914N offers versatile coil termination and voltage options with surge protection capabilities, providing flexibility in various applications. Its magnetic design ensures high efficiency by delivering significant spool actuating force per watt of power used. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube, while connector options provide protection ratings up to IP69K for enhanced environmental resilience. The valve's capacity reaches up to 8 gpm (30 L/min), with a typical response time of 50 ms and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports a switching frequency of up to 15,000 cycles per hour. Additionally, this model incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. The DNCALWN914N weighs approximately .60 lb (.30 kg) and requires an installation torque between 30-35 lbf ft (41-47 Nm). Seal kits are available for maintenance needs using Viton materials for both cartridge and coil components.

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.
