The Sun Hydraulics DNCALAV236 (DNCALAV236) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in maintaining the integrity and efficiency of pilot control circuits. With its robust design, the DNCALAV236 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 8 gpm (30 L/min), based on port 3 as the inlet and port 1 as the tank. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring long-term reliability even under strenuous conditions. It operates without requiring a minimum hydraulic pressure, adding to its versatility across various applications. The DNCALAV236 also features EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model incorporates Sun Hydraulics' unique magnetic design which enhances the efficiency of the solenoid, providing a strong actuating force per watt expended and ensuring reliable valve shifting. The wet armature design of the valve means that the working fluid surrounds the armature\u2014this is an important consideration as prolonged energization can lead to fluid degradation in certain conditions. For customization and adaptability in different environments, it offers a variety of coil termination and voltage options along with IP69K-rated connector options for enhanced environmental protection. The floating style construction employed reduces risks associated with internal parts binding due to installation torque or machining variations. This makes DNCALAV236 not only a functional choice but also a durable one in diverse operating conditions.

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.
