The Sun Hydraulics DNCALCV636 (DNCALCV636) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that excels in applications requiring reliable directional control of hydraulic fluids. This direct-acting, balanced spool valve is designed with a closed transition between positions to minimize oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. It operates effectively with port 3 as the inlet and port 1 as the tank, though it allows for reverse flow with caution as performance consistency cannot be assured. Rated for up to 5000 psi (350 bar) service, the solenoid tube assembly of this valve is fatigue rated, ensuring durability and reliability under demanding conditions. The DNCALCV636 does not require a minimum hydraulic pressure to operate, making it versatile across various hydraulic systems. Special attention is needed when selecting seals; cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids and must avoid exposure to petroleum-based substances which can degrade the seals. The wet armature design of this model means that the working fluid surrounds the armature and absorbs heat from the coil, potentially affecting fluid properties over extended periods of energization. The DNCALCV636 features multiple coil termination and voltage options, including versions with surge protection to suit diverse operational requirements. Its coils are interchangeable with other Sun Series 1 solenoid products and offer flexibility in mounting orientation. For environmental resilience, additional weatherized coils and kits are available to enhance protection against harsh conditions. The valve also incorporates Sun's floating style construction which reduces risks associated with internal parts binding due to installation errors or cavity/cartridge machining variations. With a swift response time typical at 50 ms and capable of handling up to 8 gpm (30 L/min), this model ensures efficient operation and control in sophisticated hydraulic systems.

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.
