Both pneumatic and direct acting air valves can be manufactured to have multiple outlets. Two-way pneumatic valves are quite common in space heating and cooling and 3 way valves may be used to heat multiple apartments from the same source. Pneumatic air valves are convenient for multiple-line valves because air is easily compressed and directed to different outlets using the basic principles of air compression.
