Features
This valve is a double disc structure,stem unbalanced force is small, compact structure, used for water heating (air conditioning)
system, constant differential pressure of the controlled system, and has the following features:
●Constant differential pressure of the controlled system ；
●Support the controlled system internal autonomic regulation；
●Absorbing outside net differential pressure fluctuation；
●Eliminate the logging automatically function。
●Use the advanced stepless voltage regulation structure, control pressure adjustable ratio up to 25: 1
