Top Entry Trunnion Mounted Ball Valve

Top Entry Trunnion Mounted Ball Valve

BoleiValve developed an advanced design of the top-entry ball valves, in a complete wide range of diameters and pressure classes. Top-entry valves are the perfect choice when on line maintenance is required.
With stem in vertical position it is possible to remove the bonnet the valve allowing free accessto the body cavity without dismantling the valve from the line. A set of special maintenance tools permits to take out both ball and seat-rings, this maintenance operationrequires very little space around the valve, thus allowing it in areas where space is a limiting factor.
Top Entry constructionis available in forged or cast execution, one piece symmetric body closed by a bolted bonnet. The range is both for Full and Reduced bore, pressure ANSI class from 150 to 2500 , with all possible combination of ENDS connections: flanged (RF-RTJ), butt welding and HUB ends.
