For Canada the product is gas certified Ex d IIC T6 and dust certified Class 2, Division 1, Groups E, F and G.

For the USA  the product is gas certified Class I Zone 1, AEx d IIC T6 and dust certified Class II, Zone 21, AEx tD T85^oC; IP67.

Designed for use in the oil, gas and petrochemical industries these units can be fitted to a wide range of quarter turn or linear valve actuators.

Avaialbe in stainless steel or coated alumium there is a very extensive range of monitoring equipment that can be fitted in the 007-120.

Switch options include micro switches, hermetically sealed magnetically operated reed switches and standard or failsafe inductive proximity sensors. Potentiometers of various different values can be geared or directly driven. A solenoid back wiring facility can be provided so that switches and solenoid can be wired to the control room via a single multicore cable without the requirement for a separate junction box.

For continuous feedback of valve position or for monitoring the performance of critical emergency shutdown valves during partial stroke testing, 4- 20mA, 4-20mA + HART®, PROFIBUS® PA or FOUNDATION™ FIELDBUS position transmitters are available in K4-20 variants.
