The Sun Hydraulics DNCALZV912 (DNCALZV912) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, minimizing oil loss during shifting, which is especially beneficial in pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring robust performance under demanding conditions. Notably, this valve does not require a minimum hydraulic pressure for operation and incorporates EPDM seals suitable for systems using phosphate ester fluids\u2014caution should be taken to avoid exposure to petroleum-based fluids that could damage the seals. The Sun Hydraulics DNCALZV912 employs a wet armature design, where the working fluid surrounds the armature and absorbs heat generated by the coil\u2014important to consider in applications where coils remain energized for extended durations. The valve's high-efficiency solenoid design provides significant spool actuating force per watt expended, ensuring reliable shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, coil connector options offer protection ratings up to IP69K. This model features a T31A cavity with an 8 gpm (30 L/min) capacity and exhibits a typical response time of 50 ms. It maintains maximum operating pressure at 5000 psi (350 bar) and allows up to 15000 cycles per hour switching frequency. The manual override requires a force of 5 lbs/1000 psi (33 N/100 bar) at Port 1 with an override stroke of .10 inches (2.5 mm). The valve's hex size measures .78 inches (22.2 mm), with an installation torque between 30-35 lbf ft (41-47 Nm). This model weighs .60 lb (.30 kg) and utilizes Viton seal kits 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.
