A Study about Control Valve Design Aspects for Critical Applications in Petrochemical Plants
The past, present and future of valve design and sizing Control valves – the workhorses of the control loop – mostly have to convert to 1 to 5 kW heat power (the typical pump power in chemical plants) and, furthermore, in the HPI sector to a range between 5 to 200,000 kW heat power – the typical power range with high performance pumps, flow machines or the total plant power – blocked by flare shut-off valves and control valves.
From an economical point of view, these valves often operate more or less successfully under high stress load, characterized by additional expenditure for noise-reducing insulation and devices or maintenance, r should severe problems arise, plant downtime, i.e. low or high cost of ownership.
