how the 2.5bar pressure able to control the 40bar steam
Answer Posted / mohamed yousuf(instrumentation
according to the formula P=F/A
Actually we are applying the 2.5 bar pressure to the
diaphram actuator. By increasing the area of diaphram we
can increse the force acting on the diaphram and that muuch
of force is more enough to actuate the stem movement.even
though 40 bar pressure is applied only to the small area
(plug of the control valve).the force actiong on it will be
very small.
