800X differential by-pass balancing valve structure and purpose

800X Differential By-Pass Balancing Valve is used between water supply and water back of an air conditioning system in order to balance the pressure differential and to improve the system’s utility, keep the pressure differential at an accurately constant value and to lower the system’s noise and damage to the equipment due to an extra-big pressure differential to the utmost extent. It is superior to the other balancing valves, needs no other execution machine, gets the system balanced completely dependes on the pressure differential of the medium’s own and saves energy and the installation space.
