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). |
