Features: Range: 0-25(MPa), Thread: 5/8". The pressure regulator converts high pressure gas-to low pressure gas-and keeps the pressure and flow rate of the outlet gas-stable. This welding pressure regulator can reduce, display and stabilize the pressure; When the inlet pressure and the outlet flow-change, it can ensure the stability of the outlet pressure. Made of high-quality material, overall compact structure, perfect and good sealing. High quality alloy body, voltage regulation is-stable, safe and reliable. Our air pressure regulator adopts humanized design handle. The large handle switch has a non-slip design and-is labor-saving. Specifications: Material:Metal+Plastic Size:Approx.18x15cm/7.08x5.9inch Range: 0-25(MPa) Input pressure: 15Mpa Adjustment range: 0-0.35mpa. Nominal flow: 251/min Note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
