WebbA proportional control valve is a valve used to control fluid flow rate by varying the size of the flow passage via a restrictor. The regulated flow rate subsequently adjusts parameters affecting a process in a system, mainly level, pressure and temperature. The other minor parameters include: weight, thickness, humidity, density, Ph, color and ...

Just like the PT, an FT is basically a flow meter that is able to communicate with a related valve. Again, like the PCV, the FCV opens or closes based on the required flow and the signals it receives from the FT.
Webb29 sep. 2024 · To maintain well control, back pressure is applied by routing the returns through adjustable chokes until the well flow condition is corrected. The chokes are connected to the blowout preventer stack through an arrangement of valves, fittings, and lines which provide alternative flow routes or permit the flow to be halted entirely.
