Watson Smith I/P Converters

Part of the IMI Norgren Group, Watson Smith are leading manufacturers of I/P Converters. Watson Smith I/P Converters are known for their extreme reliability, repeatability and accuracy. Just recently, the Watson Smith I/P Converter, type 422 was re-released back onto the market.

The Watson Smith type 422 I/P Converter is one of the most popular models due to its extreme durability and innovative elements, which allows the product to provide a fail freeze function. On loss of signal, this specific Watson Smith I/P Converter maintains its pneumatic output at its last output, whilst other valves would drop to zero output.

Watson Smith also manufactures I/P Converters with other features. While the type 422 is an intrinsically safe Watson Smith I/P converter with fail freeze properties, the type 140 boasts ATEX features, making it the perfect option for hazardous applications.
