Important: Starting in October, 2019, the base actuators are gradually being replaced with an updated design. Documents of the new design are marked with Release 2 – 2019. The Control Modules of the FieldQ remain unchanged.
FieldQ is an integrated rack & pinion actuator concept with a base actuator and various control modules for control and feedback signals. FieldQ are designed to operate quarter turn valves or any other quarter turn application. FieldQ consists of 9 actuator sizes (spring return or double acting) and 5 control modules for conventional wiring or with bus communication protocols like AS-Interface or Foundation Fieldbus.
ATEX, PED and Machinery Directives, FM CSA, IECEx and Inmetro. This product is only intended for use in large-scale fixed installations excluded from the scope of Directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS 2).
On/Off, Positioning, Modulating, ESD
Ball, butterfly, plug and any other quarter turn application
Standard -20°C to +80°C (-4°F to +176°F). Optional high and low temperature options
9 sizes: 47 to 1676 Nm (413 to 14874 lbf.in)
up to 8.3 bar / 120 psi
Reduce commissioning cost by the easy to mount single unit.
Provide maximum flexibility in various applications with the modular design.
Use the Q-Series Valve Operating System in compact installations benefiting from the low profile.
Prevent unplanned Plant-Down-Time using the PlantWeb™ or NAMUR NE 107 connectivity with predictive diagnostic capabilities.
A single electrical connection point, reducing wiring complexity.
One Control Module for the full actuator range, reducing stock levels of various spare parts.
One source of supply for Valve Operating Systems, reducing sourcing complexity.
Robust and durable spring-return or double-acting actuator design.
Output torque ranging from 47 to 1676 Nm (5.5barg) or 413 to 14874 lbf.in (80pisg).
Easy exchangeable cartridges for pilot valves, limit switches or booster blocks.
Standard ”Breather” function protects spring chambers for corrosion.
Proof enclosure, prevents ”hot-work-permits” or down time for switch adjustments.
