Types AQ, IQ & SQ

valve position monitorIdeally suited for hazardous area applications onshore or offshore

The types AQ & IQ and the new type SQ Valve Position Monitor Systems are ideally suited for hazardous area applications onshore or offshore.

Each type is supplied with an IP67 enclosure has a screw-on cover and a high visibility open / close position indicator all designed to minimise the total size of the automated valve package.
