The Sun Hydraulics DNDAMUN214 (DNDAMUN214) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered with a fatigue-rated solenoid tube assembly, it is capable of handling up to 5000 psi (350 bar) without requiring any minimum hydraulic pressure for operation. This versatile cartridge offers several manual override options, although it is important to note that manual override functionality is not compatible with weatherized coils. The valve features a detent mechanism in the manual override for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. The DNDAMUN214 incorporates EPDM seals suitable for systems using phosphate ester fluids but should not be used with petroleum-based fluids as they will damage the seals. Its wet armature design means the working fluid surrounds and cools the armature; however, this could affect fluid integrity over prolonged coil energization periods\u2014particularly in water-glycol mixtures that may form varnishes impacting cartridge function. This model supports various coil termination and voltage configurations, with options available for surge protection. The high-efficiency magnetic design ensures reliable valve shifting by delivering high spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, coil connector options provide ratings up to IP69K for enhanced environmental protection. The DNDAMUN214 uses Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. It fits into cavity T-31A and has a capacity of 10 gpm (40 L/min). With typical response times around 50 ms and a switching frequency of up to 15,000 cycles per hour, this valve is designed for efficient performance in demanding applications.

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.
