TECHNICAL FEATURES
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.
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.
Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage
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.

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.
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.
