All Stainless Steel Nitrogen Relief Valve product description:
All Stainless Steel Nitrogen Relief Valve produced and sold by Baigang valve group,Pressure regulator
without additional energy, the use of the media itself is the media as
the power source. Automatically control the valve medium flow, so that
the pressure after the valve~maintain a constant pressure
stabilizer. Has been widely used in continuous gas acquisition and
transportation of natural gas, urban gas and metallurgical, petroleum,
chemical and other industrial production sector.
Valve Features:
Control of high precision, general than ZZY type direct operation of
the regulator about double high. Adjust the pressure ratio (such as the
valve before 0.8MPa, valve 0.001MPa) is particularly suitable for
micro-pressure gas control.
Pressure set in the pilot~achieve, so convenient, fast, labor-saving time-saving can be run continuously set.
