Answer Posted / www.islamqa.com
x-axis is %valve stroke
y-axis is %flow rate
we have 3 versatile characteristics:
====================================
linear: flow rate is linearly proportional with valve stroke
equal percentage: flow rate increases slowly with valve
stroke
quick opening: flow rate is increasing dramatically with
small valve stroke
