Casted Trunnion Mounted Ball Valve are designed in accordance with API 6D for class 150, 300, 600, 900, 1500, 3 piece cast steel side entry design bolted connections between body and closure, trunnion bolted connection, body thickness comply with ANSI B16.34.
Series - 150 To 900
Seat ring is trunnion mounted type, spring loaded to assure the contact with ball in order to provide an effective tight seal even at low differential pressure between cavity and downstream closure. Standard design is soft seated, A different soft materials are available based on the customer working condition. Available in full and reduced Bore. Electric, pneumatic and hydraulic actuators are available based on customer requirement. Valves have been designed for use with various combinations of materials such as: Carbon steel, low carbon steel, special alloy, stainless steel, Monel, Inconel.
