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.
