In the food and beverage industries K Controls
products are used to accurately monitor or control the position of
on/off or modulating valves.
Valve monitoring and control has to be
accurate and reliable in order to ensure consistent standards of product
quality and safety.
Combustible dusts can be a hazard e.g.
flour, custard powder, instant coffee,
sugar, dried milk, potato powder and soup powder.
For this reason K Controls products can be
supplied with Ex i, Ex ed or Ex d certification, to the very latest
standards, for use in dust Zones 21 and 22.
Valves can be located outdoors or be subject
to wash down, so enclosures are rated IP66 or IP67.
Solenoid valves for on/off valve control are
sometimes located in remotely sited panels but this can lead to problems
with valve identification and lags in actuator response times. K
Controls combines one or more pilot solenoid valves for actuator control
with the position switches in the same compact enclosure local to each
actuator. The result is the 007C Control Monitor. Envelope dimensions of
the 007C and actuator assembly remain the same, the solenoid is
protected from the environment and if solenoid manual override is
specified it is “tamperproof” because it can only be accessed by
deliberately removing the cover. Solenoid function can be 3/2 single
acting, 5/2 double acting or 5/2 double acting stay put.
AS-i or DeviceNet are fieldbus systems used
the food and beverage industries. 007 Switchboxes or 007C Control
Monitors can be provided with integral field addressable AS-i or
Control valves are widely used to control
process temperature and they also play an important role in the storage,
pumping and mixing of liquids for food and beverage production.
K Controls can supply a wide range of
positioners. The K4-20 range of position transmitters can be also used
to monitor valve performance.
A wide range of waterproof connectors can also
be supplied that allow actuated valve assemblies to be quickly removed
from the line for servicing.
