K Controls AExd and Explosion Proof Valve Position Monitors are now comprehensively certified for use in the USA and Canada.
The products have been designed to accommodate, as an option, the latest version of the top mounted highly visible Klearvision position indicator. It is directly driven from the input shaft, no internal gearing is required.
The 007-100 is a compact solution that can contain up to 2 switches or a 4-20mA position transmitter. Two point cover fixing reduces commissioning times. The larger 007-120 can contain up to 4 switches and a 4-20mA position transmitter.
Ambient temperature ranges have, where possible, been extended. Some AEx d and Explosion Proof versions can achieve -60oC to +70oC at T6 or -60oC to +120oC at T4.
For subsea use enclosures are available in a range of materials including carbon steel, 316L stainless steel, 254SMO stainless steel (20%Cr -18%Ni-6%Mo), Duplex 2205 and Super Duplex. Sub-sea connectors and cable can also be supplied.
007-100 and 007-120’s fitted with certain switches are suitable for both Low and High Demand scenario applications at SIL1 or SIL2 of IEC 61508. Versions fitted with Namur proximity sensors are suitable for both Low and High Demand scenario applications at SIL2 of IEC 61508. Versions fitted with fail safe proximity sensors and used in conjunction with safety rated barriers, are suitable for both Low and High Demand scenario applications at SIL3 of IEC 61508. Declarations of Conformity are available on request.
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.
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.
Versions certified ATEX, IECEx or INMETRO are available for use in other parts of the world.
