Durable and Safe
High-precision gear cutting methods provide close tolerances and ensure minimum gear backlash. Together with the 3-point guiding system of the pistons, this ensures an extremely long working life. For the ultimate in safety, the FieldQ also features an anti-blowout pinion. This means the teeth of the piston keep the pinion inside the housing -- eliminating any danger of "blowout" under pressure.
ATEX and Pressure Equipment Directive
The actuators have comply to the European Community's ATEX and Pressure Equipment Directive (PED), which allows Emerson Process Management to affix the CE Mark.
Covering the Most Popular Torque Requirements
A wide range of actuator sizes is available covering the most popular torque requirements. These range from 40 up to 1600Nm (355 to 14100 Lbf In). Modular spring packages are available for safe maintenance and easy adjustment to a wide variety of supply pressures, while spring return versions are supplied as "On air failure Closing" or "On air failure Opening."
Flexible and Cost-effective Valve Mounting
A range of inserts is available to enable the actuator to be directly mounted to suitable valves and to eliminate the need for a bracket and coupling type mounting kit. The use of direct mounts significantly cuts the cost of the valve/actuator assembly. The standard actuators are fitted with square drive inserts in accordance with ISO 5211 or DIN3337, but a variety of other inserts are also available. Special inserts have oversize or undersize squares, with double-D or pinion key way forms. Where direct mounts are not possible -- for instance, on valves with exposed grand packing -- the use of inserts simplifies the design of the mounting kit.
Outstanding Finish
A corrosion resistant polyester powder coat finish ensure long-term reliability in aggressive atmospheres, exceeding a 1000 hour salt spray test (ASTM B117).
