Providing Optimum Performance under all Circumstances, EL-O-MATIC
For applications involving extreme temperature ranges or corrosive chemicals, El-O-Matic actuators may be an excellent choice for your continuous process or batch conditions. Available from 40 to 120 psig air supply, these a ctuators feature dual opposed and balanced piston design for optimum performance and long life. Integrated control options include manual override, a three-position positioning system, limit switches, solenoid valves, and breather blocks.
The Smart Solution to Integrated Control, FieldQ
FieldQ pnuematic actuators greatly reduce assembly and installation costs by allowing the user or valve automation shop to integrate the actuator, solenoid valve, switch box, and accessories into one product. Covered by various patents on the control module, and the contactless position sensing, the  FieldQ revolutionizes the piecemeal approach to automated valve assembly. Upgrades are also much easier with plug in modules that eliminate the need to hang various accessories all over the assembly.
Other options within FieldQ include push-button initialization of position indicators and intelligent diagnostics to notify the operator of actuator/valve condition. In addition, digital communications are available for several standard bus protocols allowing you to harness the power of PlantWeb® for yet another facet of your operation. With FieldQ, estimating is a thing of the past, now you can know the status of your valve assembly and take control of your process.

Actuators are an essential element in any automated assembly. Each one must be carefully chosen to meet the requirements of the valve on which it is mounted and the intended application. Possibilities include pneumatic (whether rack and pinion or scotch-yoke), electric, and hydraulic actuators in a wide range of torques and sizes to meet your needs at the most economical price. In addition, application, safety factors, SIS, SIL, Partial stroke, actuation time, temperature, and emergency response must be considered to optimize the assembly to your needs. Caltrol's AVS Division stocks a large variety of actuator lines and models in order to handle almost any actuation requirement that you may have both quickly and efficiently. 
It’s already proven. To start with, EIM didn’t reinvent the wheel. Instead of devising a completely new actuator, they simply equipped their well-established Series 2000 actuator with all the features needed to offer Total Electronic Control (TEC) in a true non-intrusive package.
