Three way type ball valve
L type three way ball valves are used to switch directions of medium flow and can have two intervertical passages linked.
T type three way ball valves are used to divide, combine or swith directions of medium flow, T type bore construct can make the three passages or two of the three passages linked.
Three way ball valves, generally speaking, adopt a two seats construct and can also use four seats construct and can also use four seats construct according to user’s requirement.
