Emerson Updates Fieldvue Digital Valve Controller

Emerson Process Management has introduced the latest version of its Fieldvue digital valve controller. The diagnostic capabilities of the DVC6000 Series instrument monitor valve performance, allowing plants to operate for between five and seven years between maintenance shutdowns.

That is an improvement compared to the traditional schedule of 12-18 months between shutdowns. The partial stroke testing capabilities of the DVC6000 ensure the readiness of shutdown valves.

According to the company, the partial stroke test technology has earned two patents, as well as Exida, TUV (Germany) and SIL-3 certification and approval. The instrument may also be installed via 'hot cutover', which facilitates the conversion from analogue to digital without interrupting the production process.
