Instructions for use:
ZZC and ZZV self-operated differential (micro) pressure control valves are actuator products that do not require additional energy. It can be used for nominal pressure PN01 and PN10. The differential (micro) pressure can be adjusted in sections. From 50mm . W.C to 0.1MPa. It is very versatile and can be used in industrial combustion systems to control the ratio of two materials, such as gas and air flow, to achieve ideal combustion. It is used for sealing oil system for hydrogen-cooled generator sets. When the low pressure end of the differential pressure valve is connected to the atmosphere, it is a micro pressure valve (negative pressure of the differential pressure valve, end pressure, and force is zero).
Product features:
Adjustment of the set value without stopping production;
There is no packing, there is no friction when the valve stem is moving, and the upper seal is good and reliable;
The sensitive ground parts of the actuator are extremely sensitive, and the slightest pressure change will be sensed;
The valve body is a four-way form, and one type of valve body can be used because of the surface K and B types.
