ZZC and ZZV Self-poor (micro) is a pressure regulating valve actuator does not require external energy products. It can be used for nominal pressure PN01, PN10. Poor (micro) pressure can be sub-regulation. From 50mm.W.C to 0.1MPa. Its use is widespread, it can be used in industrial furnace systems, control of two materials, such as gas, air flow ratio, in order to achieve ideal combustion. Hydrogen-cooled generator set for seal oil system, control between the differential pressure seal oil with hydrogen in order to ensure reliable seal. When the low pressure side of the differential pressure valve through the atmosphere is micro-pressure valve (differential pressure valve negative pressure, end pressure, force is zero).
Features
* No need to stop production to adjust the set value;
· No filler, the stem, there is no friction when the next activity on the seal is absolutely reliable;
· Actuator sensor is extremely sensitive, tiny pressure changes are sensed it;
· Body of Stone form, thus K, B-type can be common one kind of body.
