Valve positioning - petrochemical refinery
VALVE POSITIONING AT A PETROCHEMICAL REFINERY
In applications where pneumatic positioners are still in operation, it is increasingly required that the control and position of the valve is able to be controlled remotely through an electronic 4-20mA signal.
A field-mount I/P offers the flexibility to connect to pneumatically operated positioners and add the flexibility of control required through its electronic control signal.
The type 140 failsafe Electronic I/P Converter has EExd certification for global use, and with its integrated filtration and weatherproof protected electronics, it has been designed for the typical refinery conditions and environments.
The type 140 has been proven in use over many years, demonstrating its level of reliability and precision control.
