K Controls AExd and Explosion Proof Valve Position Monitors now certified for use in USA and Canada

10 August 2015

The 007-100 is a compact solution that can contain up to 2 switches or a 4-20mA position transmitter. 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.

007-100 and 007-120 AExd and Explosion Proof Valve Position Monitors now carry the following certification:

USA:
*Class I, Divisions 1 & 2, Groups B, C and D. Class II, Groups E, F and G. Class III. T4/T6; Type 4, 4X, 6 and 6P.
*Class I, Zone 1, AEx d IIC T4/T5/T6. Zone 21, AEx tb/tD. IIIC T135oC/T100oC/T85oC. IP66/67/68 and/or Type 4, 4X, 6 and 6P.

Canada:
*Ex d IIC T4/T5/T6. Ex tb IIIC T135oC/T100oC/T85oC. Class II, Groups E, F and G. IP66/67/68 and/or Type 4, 4X, 6 and 6P.

The enclosures are supplied in either coated aluminium or ANC 4B (316) stainless steel.

Both Baseefa and CSA have issued K Controls with ingress protection test reports.

Baseefa:  Enclosures have passed IP 66, IP67 and IP68 tests to EN 60529:1991. IP 68 at a depth of 30 metres for 96 hours. Standard units are rated IP66 and IP67. IP68 versions are available to special order.

CSA: Nema Enclosure Types 4, 4X, 6 and 6P.

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.

There is a very extensive range of monitoring equipment that can be fitted in this range of Position Monitors.

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.

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.
