①Selection of 3-way ball valve
There are two types of three-way ball valves: L port and T port. Each port can be used as follows.
②Piping simplification and cost reduction
The 3-way ball valve has three flow paths, and is used for fluid switching, shunting, and mixing. This simplifies the piping system using a large number of 2-way valves, and reduces costs, leading to improvements in equipment and the cost reduction.
③Actuator selection according to application possible
Depending on the application, manually operated, pneumatically operated or electrically operated actuator can be applied.
