if we open the inlet of an air regulator ,how it will affect
the out put of regulator? (out put of regulator is using to
operate an on-off valve.it is an air to open valve,and valve
is in open position.my doubt is air regulator will hold the
valve in open or not,if there is no consumption or leak in
regulator out put side ,we only loose the input pressure.)

Answer Posted / sandeep modi

If you open the inlet of air regulator,no pressure will hold
at air regulator,the pressure will go to zero and your air
to open valve will close.

But when you stop the supply of inlet air(not open the
supply) the pressure of AFR will be hold at that
condition,and if you valve is in open condition ,it will
remain open.
