Controlling the valve
The -way ball valve is very well suited for automation. By replacing the handle with a Z-key, the valve can be electrically controlled or by pneumatic activation (NO, NC or DA).
The housing of the valve is available in Stainless Steel, Brass and normal steel.
T-Port & L-Port 3-Way Ball Valves
Three-way ball valves are most commonly configured with L-Port or T-Port flow patterns. The ball valve is drilled into a specific design, creating either an L- or T-shaped port.
Each design serves a specific function. An L-port valve draws media from multiple sources or diverts media between two different destinations. A T-port valve serves a very similar function, the main difference being that in the normal position the media will flow straight through from one side of the T to the other.
The T-port can also be configured to have media flow directly through the valve in position #1 and all ports open in position #2. An L-port valve cannot be configured to have all valve ports open simultaneously.
