The feedwater valve is not classed as a full shut off valve (bubble tight). However, the tolerances are set very tight thus restricting flow through the valve. For this reason it is advised to place a normally closed solenoid valve in series with the feedwater valve. The further advantage of this is that in the event of a power failure, the feedwater valve will remain in the position at loss of power, however, the normally closed solenoid valve will shut off restricting flow to the boiler.
