The Sun Hydraulics DNCATAV536 (DNCATAV536) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve is notable for its closed transition between positions, which significantly reduces oil loss during shifting, making it ideal for pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it may not deliver optimal performance. Rated for a fatigue service pressure of 5000 psi (350 bar), this valve does not require minimum hydraulic pressure to function due to its direct actuation. The DNCATAV536 features a wet armature design where the working fluid surrounds the armature, potentially affecting operation if the coil remains energized over extended periods. This can be particularly relevant with water-glycol mixtures that may degrade at high temperatures. The valve offers various coil termination and voltage options, some with surge protection. Its high-efficiency solenoid design provides substantial spool actuating force per watt, ensuring reliable shifting. The cartridge incorporates Sun's floating style construction to prevent internal part binding from excessive installation torque or machining variations. It fits within a T-31A cavity and belongs to Series 1, boasting a capacity of 8 gpm (30 L/min). The valve demonstrates rapid response times of approximately 50 ms and is capable of handling up to 15,000 cycles per hour. Additional features include interchangeable coils compatible with other Sun Series 1 products and multiple coil connector options rated up to IP69K for enhanced environmental protection. The installation requires a torque of 30-35 lbf ft (41-47 Nm), and the unit weighs approximately .60 lb (.30 kg). For systems using phosphate ester fluids, EPDM seals are recommended; however, these seals are incompatible with petroleum-based substances.

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.
