Emerson Process Management has introduced the Enardo 850/950 series of wirelessly-monitored pressure vacuum relief valves (PVRVs) that provide safety and emissions control by managing the pressure in storage tanks.
The pressure in storage tanks in the oil and gas, chemical, petrochemical and pharmaceutical industries fluctuates due to changes in temperature, liquid level, or both, and 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, and site managers are increasingly looking for ways to increase safety and efficiencies.
Emerson’s new wireless solution enables immediate response to prevent problems related to safety, emissions, and the quality of a tank’s content.
“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,” said Steve Attri, product manager for Emerson Process Management.
