Features: High quality full copper body, pressure regulation is stable, safe and reliable. Pressure regulator turns high pressure gas into low pressure gas, and keep the output gas pressure and flow rate stable. It can reduce, display and stabilize pressure; when inlet pressure and outlet flow change, it can guarantee the stability of outlet pressure. Compact structure, pressure gauge and high pressure gauge are made of high quality material, overall compact structure, perfect, good sealing. Mainly used for gas welding, agricultural plant culture, chemical industry and so on.
