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.

TECHNICAL FEATURES
The soft shift cartridge is interchangeable with the standard cartridge, however, the performance limits are lower.
The soft shift feature can greatly reduce shock due to valve actuation but should not be counted upon in applications where timing is critical. If you need accurate
ramping or timing control, consider Sun's electro-proportional valves.
The soft shift feature results in significant increase in response time over Sun's standard solenoid. Response time is dependent on flow, pressure, coil voltage, oil
viscosity and ambient temperature. Typical response time ranges from 150 ms to 300 ms.
For consistent soft shift performance, port 1 should be at a positive pressure.
This valve includes a push-type manual override control. Other manual control options such as T or D, cannot be ordered with the soft shift control but can be
installed easily in the field. See Twist/Lock Manual Override link above for details. Please note: Manual override functionality is not compatible with weatherized
coils.
The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
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.
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.
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.
