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.
