The Sun Hydraulics DMDATPN814N (DMDATPN814N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust service with a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for the same. The valve features a unique closed transition spool setup between positions B and R, enhancing performance by providing faster and more consistent response times during operation. This makes it particularly suitable for applications requiring precise control with minimal hydraulic pressure. The DMDATPN814N operates efficiently without any minimum hydraulic pressure, thanks to its direct actuation design. It includes options for manual override controls labeled D, L, and T, which are intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature which helps in heat management but requires careful selection of fluid to avoid breakdown or varnish formation that could impair functionality. Additionally, this model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based substances as they can cause damage. The interchangeable coils from Sun Series 1 solenoid products add versatility to this component by allowing mounting in either direction on the tube. Incorporating Sun\u2019s floating style construction minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 12 gpm (45 L/min), typical response time of 50 ms, and very low maximum valve leakage at high pressures, this valve is an excellent choice for demanding hydraulic applications requiring reliable directional control and rapid switching capabilities.

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.
