Details
In closed pipelines, this type of control valve maintains the pressure difference between the supply and return pipes within an adjustable range.
■ Features
● As an air open differential pressure control valve, the valve opens when the inlet pressure increases. The pressure difference is adjusted by a valve installed between the supply and return pipes.
● Due to its automatic control type, no other auxiliary power supply is required.
● It has good balance and maintains a minimum set pressure difference based on pressure changes.
● Compact design with long service life.
● Easy installation and operation.
● Due to the diaphragm separation system, it is not affected by temperature and thus has a long service life.
