ZZV/ZZC Micropressure Regulator

It doesn’t require any external energy, but use the pressure of Medium to operate itself, so that pressure can be maintained at a constant value. For example, in the industrial furnace gas combustion systems, it is always used to control two types of fuel mixture ratio to achieve optimum combustion conditions. It also can be used as gas, natural gas, liquefied petroleum gas, ammonia, nitrogen, oxygen and other industrial gases in decompression, micro-pressure differential pressure regulation system. What ‘s more, it also is used for hydrogen-cooled generator seal oil system to control the pressure difference between oil and hydrogen, in order to ensure reliable seal.
