The Sun Hydraulics DNCATAV236 (DNCATAV236) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. It is specifically engineered for applications requiring minimized 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, though reverse flow is possible but not recommended due to potential performance degradation. This robust valve operates effectively without any minimum hydraulic pressure requirement and is fatigue-rated for up to 5000 psi (350 bar) service. The DNCATAV236 utilizes a wet armature design that allows the working fluid to surround the armature, which can impact fluid stability if exposed to prolonged coil heat. This characteristic requires careful consideration of fluid types used, especially with water-glycol mixtures that may degrade over time. The solenoid's magnetic design ensures high efficiency, providing substantial spool actuating force per watt expended for reliable operation. Additionally, it offers various coil termination and voltage options with available surge protection. The valve's construction incorporates Sun's floating style to minimize internal part binding due to installation torque or machining variances. It supports a switching frequency of up to 15,000 cycles per hour and has a typical response time of 50 ms. For manual operations, it requires an override force of 5 lbs/1000 psi at Port 1 with a stroke of .10 inches (2.5 mm). The DNCATAV236 also features interchangeable coils compatible with other Sun Series 1 products and provides environmental protection options with IP69K-rated coil connectors. With a maximum capacity of 8 gpm (30 L/min) and minimal leakage rates under specified conditions, this valve serves as a reliable component in hydraulic systems demanding precise control and durability.

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.
