3-way Butterfly Valve, Manual

Two butterfly valves with a central outlet serve as "vacuum manifolds." The lateral ports come in various flange sizes. The two independent valves enable 4 switch states, corresponding to "T" and "L" ball valve versions. Semi-open positions are also possible. In contrast to a ball valve, this valve can be used in HV environments, but not at overpressure.
