Overview Image


The cover of top-entry ball valve can be disassembled from the body of the valve, so all parts can be easily maintained or replaced in-line. On demand, trem, trunnion and ball can be made as a monobloc piece. This option increases the reliability of the valve. This construction allows more flexibility in customization of driving train design, allowing for example the mounting of an actuator directly on the bonnet without an intermediary bracket.
