2-way, soft shift, solenoid-operated directional spool valve - pilot capacity
Capacity:
.25 gpm (1 L/min.)
Functional Group:
Products : Cartridges : Solenoid Operated : 2-Way : Spool - Soft Shift
Model:
DAALS
Product Description
This solenoid-operated 2-way, 2-position cartridge is a direct-acting, balanced spool valve with a soft shift feature. The soft shift feature greatly
reduces system shock due to valve actuation. The valve is available in either a normally open or normally closed configuration.
This cartridge can be installed directly into a cavity in the end of many of Sun's pilot operated and ventable valves to provide integrated pilot control.
Technical Features
The soft shift cartridge is interchangeable with the standard cartridge,
however, the performance limits are lower.
The solenoid tube assembly is fatigue rated for 5000 psi (350 bar)
service.
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.
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 soft shift feature results in significant increase in
response time over
Sun's standard solenoid. Response time is dependant on flow, pressure,
coil voltage, oil viscosity and ambient temperature. Typical response
time ranges from 150 ms to 300 ms.
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.
For consistent soft shift performance, port 1 should be at a positive
pressure.
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 valve comes with a 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
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.
