Product introduction FLOWSPEC 800X type differential pressure balancing valve is applicable to be mounted between the air-conditioning system water supply and backwater to balance their differential pressure. 800X type differential pressure balancing valve can increase the system operating factor, keep precise differential pressure steady value, and even reduce mostly the system noise and the system damage caused by over differential pressure. 800X type differential pressure balancing valve is superior to other balancing valve, because it doesn’t need actuator, but only depends on the medium self differential pressure to achieve balancing system function, so that 800X type differential pressure balancing valve is one type of energy conservation and space saving intelligent valve.
