Problem Statement
Customer required a control valve which had a high pressure drop from 81 bar inlet pressure to 1 bar outlet pressure for Water treatment specialist for a Sugar Plant in Northern India
Solution
To develop a control valve with a trim design having up to 13 stages of pressure drop.
To sustain the high pressure drop, we designed a multi-path, multi-stage trim with axial flow along with plug having grooves for achieving good controllability at lower lifts.
The pressure reduction is through axial slots
The gradual increase in flow capacity (Cv) in each stage ensures that the trim exit velocity is low. The no. of pressure drop stages are selected in such a way that there is no cavitation at any stages.
Operating Parameters
Benefit
The control valve with our designed trim is working without any shutdown for more than 24 months, thus saving on the production loss and also cost of spares being bought frequently.
Economics
The total cost of this valve is 20%-30% less than the competitor product
