K Controls submersible valve position monitors can be fitted to a wide range of 1/4 turn or linear, sub-sea valve actuators.
4–20mA + HART® 5 or 7, PROFIBUS PA or FOUNDATION FIELDBUS signals can be provided to continuously monitor valve position. End of travel proximity sensor inputs are also an option.
When not submerged, the Exi or Exd, ATEX and IECEx-certified position monitors could be in an area where hazardous gasses are present. Ex versions have been independently tested by SGS Baseefa, IP68 to EN 60529:1991, at a depth of 30m for 96h. Most other units are designed for depths to 150m and special pressure balanced units are available for depths to 2500m.
Valve 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. Optional surface coatings of the carbon steel and 316L stainless units include NORSOK M501 Rev 6 System 7B (Sub-sea) paint. A standard M20 or ½” NPT conduit entry is provided. Alternatively, the base can be machined to accept a customer specified sub-sea connector or cable penetrator.
Units with multi pin connectors can be supplied with the associated cable sets that meet the exacting standards required for both subsea and shipboard use.
