Reliable Design
The patented reliable diaphragm/poppet design offers a high
air-volume capacity, suitable for the entire FieldQ range,
without requiring a booster for larger sizes. Whereas the
tolerance requirements of conventional spool or solenoid
valves demand a high air quality, this proven FieldQ
technology allows a relatively lower air quality and
therefore delivers cost savings through reducing the chance
of getting stuck. This poppet valve design can operate with
dirtier air by the use of static seals. This also causes
less wear and therefore more reliability.
Trouble-free Operation of the Actuator
The large diaphragm ensures reliable opening and closing of
the poppet and consequently ensures trouble-free operation
of the actuator -- even at sub-zero temperatures. Moisture
in the air has the potential to freeze and block in the case
of spool valves, but the FieldQ is able to overcome this
problem through the use of the diaphragm/poppet design. This
concept also enables the use of a low-power pilot valve
(1.3W) while still maintaining a fast response time.
Integrated Breather
Other beneficial features include integrated breather
functionality. This provides protection of the actuator
spring chamber in applications where the actuator is located
in a corrosive atmosphere. Without this safeguard, the
corrosive atmosphere would be sucked into the actuator
during the spring stroke and could result in long-term
damage and failure.
Integrated Speed Control
Integrated speed control is supplied as an option with
single acting versions, while double acting versions can be
equipped with standard G1/4" or 1/4" NPT throttles.
