Emerson Process Management has introduced the Enardo 850/950 series of wirelessly-monitored pressure vacuum relief valves (PVRVs) to the tank storage market.
The valves provide safety and emissions control by managing the pressure in storage tanks in the oil and gas, chemical, petrochemical and pharmaceutical industries.
The pressure in storage tanks fluctuates due to changes in temperature or liquid level. A PVRV opens and closes in response to these pressure fluctuations to ensure that safe pressure levels are maintained. However, because these PVRVs are located on the top of storage tanks, they are difficult to monitor.
The wireless valves by Emerson allows for an immediate response to prevent problems related to safety, emissions, and the quality of a tank’s content.
Product manager Steve Attri says: ‘Until now, PVRVs have remained unmonitored, with no feedback loops commonly seen in other pressure control devices. As the tank’s primary pressure control device, this wirelessly-monitored solution can be invaluable.’
