The Sun Hydraulics DNCATAV936 (DNCATAV936) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. Its closed transition between positions significantly reduces oil loss during shifting, making it particularly beneficial for pilot control circuits. The valve is optimized for operation with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to performance variations. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service and operates without requiring minimum hydraulic pressure. Cartridges equipped with EPDM seals are compatible with phosphate ester fluids, but exposure to petroleum-based substances can damage the seals. The wet armature design allows the working fluid to surround the armature, which can be influenced by coil heat during prolonged energization, potentially affecting fluid integrity in certain mixtures like water-glycol. This high-efficiency solenoid provides substantial actuating force per watt, ensuring reliable valve shifting. Coils are interchangeable within Sun Series 1 products and can be mounted bi-directionally on the tube. A variety of coil termination and voltage options are available, including configurations with surge protection and weatherized options for enhanced environmental protection up to IP69K ratings. The valve incorporates Sun's floating-style construction to minimize internal part binding due to installation torque or machining variations. The DNCATAV936 has a capacity of 8 gpm (30 L/min), a typical response time of 50 ms, maximum valve leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), and supports a switching frequency of up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs at 1000 psi (33 N at 100 bar) with an override stroke of .10 inches (2.5 mm).

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.
