Fundamental regulation failure: The physical principle of the pressure reducing valve determines that it cannot output a pressure higher than the inlet pressure. When the expected set pressure approaches or exceeds the actual inlet pressure, the valve will lose its regulating ability, and the outlet pressure can only follow the fluctuation of the inlet pressure, resulting in insufficient driving force, slow or incomplete action of downstream pneumatic equipment.
Flow supply bottleneck: Even if the set pressure is lower than the inlet pressure, if the inlet pressure margin (the difference between the inlet pressure and the outlet set pressure) is too small, it will severely limit the maximum flow rate of the pressure reducing valve. When the instantaneous gas consumption of the equipment increases, the outlet pressure will drop sharply, causing the equipment to malfunction.
