The Sun Hydraulics DNDAMYV814 (DNDAMYV814) is a solenoid-operated 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve does not require a minimum hydraulic pressure for operation, making it versatile for various applications. It features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The valve offers multiple manual override options, including configurations without manual override, though manual override functionality is not compatible with weatherized coils. For models with D or L control, the detent mechanism allows temporary actuation with a life expectancy of approximately 7,000 cycles. The DNDAMYV814 incorporates a wet armature design where the working fluid surrounds the armature, which can be affected by prolonged coil energization due to heat generation. This feature requires consideration of fluid types to prevent varnish formation that could impair function; EPDM seals are recommended for phosphate ester fluid systems but are vulnerable to petroleum-based fluids. The cartridge supports a variety of coil termination and voltage options, enhancing adaptability across different system requirements. The solenoid's magnetic design ensures high efficiency and reliable valve shifting by providing significant spool actuating force per watt expended. Additionally, the DNDAMYV814 features Sun's floating style construction to reduce risks of internal binding from excessive installation torque or machining variations in cavity/cartridge interfaces. With a capacity of 10 gpm (40 L/min) and response time typically around 50 ms, this cartridge is suitable for applications requiring quick and precise directional control. It also boasts interchangeable coils with other Sun Series 1 products and offers coil connector options rated up to IP69K for enhanced environmental protection.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges 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.
