GPM These types of valves are commonly used for pressure control applications and are most suitable for applications where a high variation in pressure drop is expected.
Quick opening valve characteristics A quick opening valve plug produces a large increase inflow fora small initial change in stem travel. Near maximum flow is reached at a relatively low percentage of maximum stem lift. Quick opening plugs are normally utilized in two position “On-Off” applications but maybe used in some linear valve applications. This is possible because of its initial linear characteristic at a low percentage of stem travel. The slope of this linear region is very steep which produces a higher initial gain than the linear plug but also increases the potential instability of the control valve.
