From extraction wells to transport pipelines within refineries and subsequently to destination sites, hydrocarbons cross numerous process valves.
Along gas and oil pipelines, process valves are installed outdoors, subject to temperatures that can be extreme in some cases, and which are almost never manned. These valves can remain in the open position for extremely long periods of time, ready to act rapidly if it becomes necessary to isolate the line.
In processing plants, in addition to shut-off functionality, there is also regulation, to control the quantity of product required for a specific operation.
Duplomatic solutions include regulators and on-off actuators, tip blocks, positioners and control units for the management of process valves, guaranteeing maximum reliability, precision and control.
