The Sun Hydraulics DNCALWV614 (DNCALWV614) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This directional valve is engineered for applications requiring minimal oil loss during position transitions, making it particularly suitable for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is technically possible but not recommended due to potential performance issues. The solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), and the valve operates without needing a minimum hydraulic pressure. This model incorporates EPDM seals intended for systems using phosphate ester fluids; contact with petroleum-based fluids can damage these seals. The wet armature design allows working fluid exposure to coil-generated heat, which can affect fluid integrity over time, especially in water-glycol mixtures. The solenoid's magnetic design enhances efficiency by providing substantial actuating force per watt consumed, ensuring reliable operation. The DNCALWV614 offers various coil termination and voltage options, including weatherized versions for enhanced environmental protection. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Connector options provide protection ratings up to IP69K. With a cavity size of T-31A and a series designation of 1, this valve supports capacities of up to 8 gpm (30 L/min) at maximum operating pressures of 5000 psi (350 bar). Typical response times are around 50 ms, with maximum leakage rates at specified conditions being 10 in\u00b3/min (160 cc/min). It supports switching frequencies up to 15,000 cycles per hour and features manual override capabilities requiring specific force and stroke dimensions. The valve construction minimizes internal part binding risks due to installation or machining variations.

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.
