The ZZC (V) self operated differential (micro) pressure regulating valve is a kind of actuator product which does not need additional energy. It can be used for nominal pressure PN01, PN10. Differential (micro) pressure can be adjusted piecewise. From 50mm.W.C to 0.1MPa. Its application is very extensive and can be used in industrial combustion furnace system. Control two kinds of materials, such as gas and air flow ratio, so as to achieve ideal combustion. It is used for sealing oil system of hydrogen-cooled power generation unit to control the pressure difference between sealing oil and hydrogen to ensure reliable sealing. The low pressure end of the differential pressure valve is a micro pressure valve (negative pressure, differential pressure, zero force).
There are two types of differential (micro) pressure regulating valves, B and K. The initial position of the B valve spool is always open, and the differential (micro) pressure is closed when it increases. The initial position of the K valve spool is usually closed and the differential (micro) pressure increases when it opens.
Characteristic
No need to stop production, that is, setting the value adjustment.
No packing, no friction exists when the stem is moving up and down, and the upper seal is absolutely reliable.
The actuator is sensitive and sensitive, and tiny pressure changes will be detected.
The valve body is in the form of four links, so K and B can be used for a valve body.
application
A. hydrogen cooled generator seal oil system;
Circulating air volume control of B. fan heating system;
C. two gas flow ratio control;
D. pump bypass regulation
