how the 2.5bar pressure able to control the 40bar steam
Answer Posted / waseem ahmad
Mr. Bipinchandra is right but there are more possible
answers to this. 1) what is the differential pressure across
the valve? the pressure of steam might be 40kg but the
pressure of steam across the valve might not 40kg. 2) the
use of balanced plug in control valves allow us to control
high pressure fluids with minimum actuator force.
