Abstract: A pressure reducing valve may include a valve body, a connecting tube, and a pressure-reducing member. The valve body is a three-way intercommunicated valve body which respectively forms into a water inlet end, a water outlet end, and a pressure-reducing tube. The connecting tube is connected to an extending section thereof, and at least a first annular groove is formed at an outer periphery of the extending section for disposing an O-ring thereon. An annular surface formed between the connecting tube and the extending section is faced to the extending section. The pressure-reducing member is hollow and has a closed end and an open end, and a buffer block is installed therein. The open end is abutted against the annular surface of the extending section, and a coupled portion between the open end and the annular surface is welded together to form a welding portion therebetween.
