Differential Pressure Controllers -- STAP-T
Relying on its own high and low pressure chamber pressure changes to change the valve opening, automatic constant pressure difference, no external power source. The valve has a shutdown function, which can set the pressure difference on site and has a large controllable pressure difference range. With high pressure chamber vents, this valve is mainly used for air conditioning and heating systems.
