Technical Features
The solenoid tube assembly is fatigue rated for 5000 psi (350 bar)
service.
A wide variety of coil termination and voltage options are available.
This valve is direct actuated and requires no minimum hydraulic
pressure for operation.
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.
Valves exhibit extremely low leakage rates; less than 10 drops/min. @
5000 psi (0,7 cc/min @ 350 bar).
Coils are interchangeable with other Sun Series 1 solenoid products
and can be mounted on the tube in either direction.
Suitable for load holding applications.
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.
This cartridge has several manual override choices, including no
manual override. See Option Selection below.
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.
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
of the cartridge.
