Three Way Ball Valve
(Panel Mountable with Live Load System)
Series : VB91
DAWSONS-TECH® Ball Valves Series : VB91 with Live Loaded PEEK Seat provides repeated leak tight shut off and also compensate for wear and pressure / temperature fluctuations during its operations. This Valves are most suitable to be used in Fluid / Gas Control System in wide range of industrial segments. This Valves can be used for diverting the flow of Fluid / Gas utilized in industries like Process and Instrumentation. The Three-way Ball Valves are designed to inlet the media through the bottom port and direct it out from any of the two outlet ports. These Valves are also used to inlet the media from either of two inlet side ports and divert it through a single bottom outlet port.
