Features
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.
