Top Entry Trunnion Mounted Ball Valves

Top entry ball valve
Top entry ball valves are of rigid body design and allow easy access to the internal area. Suitable for all topside and sub-sea applications.
A top entry ball valve comprises a plug element having two curved sides and two inclined flat sides which contain the ball and two seats. The valve body includes a cylindrical bore which is perpendicular to the axis of the inlet and outlet ports of the valve. The plug element is biased into the cylindrical bore, whereby the inclined sides of the plug element act against the inclined sides of the cheek elements to produce an axial force on the seats and the ball to form a leak-proof valve assembly.
