Stucture and purpose
A valve used between water supply /back of an air conditioning system in order to balance the pr essure differential and able to raise the system'sutility,keep the pressure differential at an accurately constant valve and to lower ths system's noise and the damage to the equipment due to an extrabigpressure differential to the utmost extent.It is superior to the other balancing valves,needs inc other execution machinery ,gets the system balancedcompletely depening on the pressure differential of the medium's own and saves energy and the installation space.
