The Sun Hydraulics DMDAMPV848 (DMDAMPV848) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for various demanding hydraulic applications. The valve features a unique closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. This model boasts a robust design with the solenoid tube assembly being fatigue rated for 5000 psi service. It operates without the need for minimum hydraulic pressure, enhancing its versatility across different hydraulic systems. The DMDAMPV848 can be manually overridden using controls D, L, or T; however, these are intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids. Additionally, the wet armature design ensures that the working fluid surrounds the armature which may affect fluid integrity under prolonged energization due to heat exposure. Interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. The incorporation of Sun\u2019s floating style construction minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With specifications including a flow capacity of up to 12 gpm (45 L/min) and typical response times as quick as 50 ms, this valve is an efficient choice for high-frequency operational needs up to 15,000 cycles per hour.

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.
