The Sun Hydraulics DNCATBN636 (DNCATBN636) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional configuration. This valve is specifically designed with a closed transition between positions to minimize oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow is not recommended due to potential performance issues. The solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), ensuring robust service in demanding applications. Importantly, this valve does not require any minimum hydraulic pressure for operation due to its direct actuated design. The cartridge uses EPDM seals suitable for systems utilizing phosphate ester fluids but should avoid exposure to petroleum-based substances to prevent seal damage. It incorporates a wet armature design where the working fluid surrounds the armature, which can be affected by heat generated from prolonged coil energization\u2014particularly with water-glycol mixtures that may form varnishes over time. A variety of coil termination and voltage options are available, including those with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The unique magnetic design of the solenoid provides high efficiency and reliable valve shifting by delivering high spool actuating force per watt expended. The valve supports coil connector options rated up to IP69K for enhanced environmental protection. This model also features Sun's floating style construction to reduce internal part binding due to excessive installation torque or machining variations in cavity/cartridge configurations. With a capacity of 8 gpm (30 L/min) and maximum operating pressure of 5000 psi (350 bar), it offers reliable performance across various applications requiring precise directional control.

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.
