This solenoid-operated 6-way, 2-position cartridge is a direct-acting, balanced spool valve. The typical use for this
valve is to select between two separate circuits. The de-energized condition connects P and T to the first circuit
and when energized connects P and T to the second circuit.

TECHNICAL FEATURES
The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
This valve is direct actuated and requires no minimum hydraulic pressure for operation.
This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is
not compatible with weatherized coils.
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.
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
NOTES
Please verify cartridge clearance requirements when choosing a Sun manifold. Different valve controls and coils require different clearances.
An additional 2.00 inches (50,8 mm) beyond the valve extension is needed for coil installation and removal.

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.
