K Controls has announced that it manufactures an extensive range of sub-sea valve actuator position monitors for on/off or modulating applications. The maximum depth of submersion for different versions is between 25 and 2500m and the enclosure material can be either epoxy coated carbon steel, 316 stainless steel or duplex stainless steel. Applications where the products are used include rig positioning, sub-sea emergency shut down or manifold valves, dry docks and tanker loading or balancing. A variety of hermetically sealed solid state or reed style proximity switches can be fitted together with 4-20mA, HART®, PROFIBUS® or FOUNDATION™ fieldbus position transmitters.
The options of non-contact sensing and component redundancy are available. ATEX 11 2 G Ex ia certification is also available should the unit be required for intermittent submersion in a hazardous area. A standard M20 or 1/2in NPT conduit entry is provided. Alternatively the base can be machined to accept a customer specified sub-sea connector.
