Sun Hydraulics Directional Spool Valve - Solenoid-operated - 3-Way - DMDAMNN

Features
 • 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
 • 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
 • 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 assemblies have a mechanical life expectancy of approximately 7,000 cycles
 • 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
