The Sun Hydraulics DMDATNV214N (DMDATNV214N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design that ensures reliable control in various hydraulic systems. The valve operates with no minimum hydraulic pressure required, making it versatile for a wide range of applications. It is particularly suitable for use as pilot controls where its closed transition between spools B and R enhances performance by providing faster and more consistent response times, although at the cost of lower capacity. This model is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The quick response time of approximately 50 ms and the ability to withstand up to 15,000 switching cycles per hour make it an efficient choice for systems requiring frequent directional changes. Additionally, the valve features manual override options with a detent mechanism designed for temporary actuation, supported by a mechanical life expectancy of about 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design aids in cooling but could affect fluid integrity if exposed to prolonged high temperatures. Interchangeability with other Sun Series 1 solenoid products offers flexibility in system design and maintenance. Moreover, the Sun floating style construction minimizes internal binding risks due to installation torque or machining variations of cavity/cartridge. This robust valve integrates seamlessly into various hydraulic circuits, providing reliable performance and durability essential for demanding applications.

This solenoid-operated 3-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.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
