The 800X Differential Pressure Bypass Balancing Valve is a valve used to balance the differential pressure between the air conditioning system supply/return. The valve increases system utilization, maintains an accurate-to-constant differential pressure, and minimizes system noise and damage to equipment caused by excessive differential pressure. The 800X differential pressure balancing valve is superior to other balancing valves in that it has no actuator, and relies entirely on the pressure difference of the medium itself to achieve the function of the balancing system, saving energy and installation space. It is an intelligent valve.
