SRI - Multiways Trunnion Ball Valve
SRi multiways ball valve can be made, on demand, with L-port, T-port or X-port. Ball valve can be designed as transflow or non-transflow. The non-transflow avoids connection of 3 or 4 branches during stroke. The SRi multiways ball valve keeps the valve tight even if the automatic cavity relief by seat leakage is actived.
