Sun Hydraulics Directional Spool Valve with Closed Transition - Solenoid-operated - 4-Way - 2-Position - DNCAMXN

Features
 • This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve
 • The transition between positions is closed
 • The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits
 • The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service
 • Valve capacity is based on port 3 as the inlet and port 1 as the tank
 • Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended
 • 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
 • 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
