Description
V260 throttling ball valves are available in
single-seal, double block-and-bleed, dual-seal, and
bidirectional flow constructions with or without
attenuators. Valves with dome-style attenuators
combine the efficiency of a rotary valve with the
noise reducing capability of a special trim (figure 4).
Valves without attenuators present little or no
restriction to flow at full travel.
