3 Way Ball Valve
A three-way ball valve has three ports or openings that are connected to piping or tubing for gas or fluid flow (media) to pass through. These ports are usually described as one inlet and two outlet ports or one outlet and two inlet ports depending upon the flow direction through the valve.
Multiport trunnion-mounted ball valve with three closures
Suitable for different flow patterns (L or T)
Used to change, divert, switch, combine or cut off the flow of different sources
Manufactured in forged or cast materials in various grades CS, SS, Duplex and all other high alloys ensuring this design can meet all our customers material requirements.
Available in standard and in low / high temperature service
