ZZCA type of self operated micro pressure valve is a type that can automatically adjust the pressure difference of one or two media without the need for external energy, maintaining the pressure difference at Value, such as in industrial furnace gas combustion systems, is used to control the mixing ratio flow regulation of two fuels A and B, achieve ideal fuel regulation, save fuel and investment, and can also be used as a pressure reduction, micro pressure, and differential pressure regulation system for various industrial gases such as gas, natural gas, liquefied petroleum gas, ammonia, nitrogen, oxygen, etc. It can also be used in the sealing oil system of hydrogen cooled generator sets to control the pressure difference between the sealing oil and hydrogen gas to ensure reliable sealing.

Micro pressure control valve can be used as a substitute in front of itZZYP-16K IIType with commander operated self operated pressure regulating valve

When the low-pressure end of the differential pressure valve is open to the atmosphere, it becomes a micro pressure valve (see Figure 2)ZZCType self operated differential pressure regulating valve andZZVThe main characteristics of the self operated micro pressure valve are:

1 For single seat micro (differential) pressure valves. If the pressure in front of the valve is ≥100kpaThen installZZYPSelf operated decompression to ≤100KpaTherefore, it can be used in situations with particularly low pressure (such as0.5Kpa）.

2 The original components of the actuator are extremely sensitive, and even tiny pressure changes can be detected,

3 Pressure regulation is extremely convenient, and setting values can be adjusted without stopping production,
