Answer» Right answer is (a) When STEAM demand is fluctuating To explain I would say: Whenever the steam demand is fluctuating, it BECOMES very difficult to maintain uniform PRESSURE. In such of these cases pressure reducing valve is made utilized by connecting to steam supply line. FUNCTION of the pressure reducing valve is to maintain constant pressure on the delivery side of the valve with the fluctuating boiler pressure.
