RTZ-GQ Pressure Regulator with Precision Regulation

RTZ-GQ Pressure Regulator also called RTZ-GQ gas regulator. Its outlet pressure control adopts automatic overpressure cut-off system. This product has precise pressure control performance and prompt response capability. Its pressure setting system is very simple. Besides, it is convenient to install and maintain.

RTZ-GQ gas regulator is suitable for various gas distribution, such as natural gas, coal gas, liquefied petroleum or propane gas and other non-corrosive gases. It is commonly used in small gas boilers, industrial furnaces, gas pressure regulating and metering stations. RTZ-GQ pressure regulator has a broad range of sizes. The specifications of this regulator can be customized according to your requirement.
