The Key Role Of Nominal Diameter In The Selection Of Stainless Steel Ball Valves
Date: | Read: 15
Generally speaking, when the nominal diameter is not greater than DN50, a rotor-type water meter should be used; when the nominal diameter is greater than DN50, a 3000 psi ball valve-type water meter should be used; when the flow rate of the water meter varies greatly, a double-type water meter should be used. Wet-type water meters should be given priority in interior design.
