Beijing Aimoke Gas Equipment Co., Ltd. (17% VAT) has years of operational and practical experience in the use of gas pressure regulators/reducing valves/regulators. The understanding of the American FISHER R622-DFF and R522 regulators is as follows: ◆R622-DFF regulator technical parameters: inlet pressure is around 2KG, outlet pressure is approximately 3KPA; flow rate can reach 30 cubic meters, with a caliber of 6分, i.e., DN20. It is an excellent secondary pressure reducing valve for liquefied petroleum gas and natural gas (Qin Jin Tel: 18210758516) ◆Built-in safety relief device ◆Simple pressure setting ◆Uses special long-life component materials ◆High regulation accuracy ◆Inlet pressure up to 17bar ◆Can be used for natural gas, air, and other gases ◆It is a very good primary pressure reducing valve for combustion machines and burners.
