Trunnion Mounted API6D Ball Valve

Short Description:

Trunnion ball valves have the obturator bounded by trunnion which prevents axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball, the contact between surfaces generates the valve sealing; trunnion standard construction ensure automatic cavity relief in case of overpressure in body cavity; these valves can be selected for a wide range of applications with no specific limits to all sizes and pressures.

Working Type: Ball valves utilise a hollow ball that allows a flow through it when in the open position and isolates when closed. The ball is driven via a spindle that fits into a slot milled into the hollow ball, which in turn is operated by a lever to open and close the ball. The ball valve spindle is encased in the valve body neck and is sealed by a range of neck seals, to prevent leakage, in addition, the ball is sandwiched between two body/ball seats that ensure positive sealing.
Applications: • Ball Valves are used for flow and pressure control and shut off for corrosive fluids, slurries, normal liquid and gases.
• They are used in the oil and natural gas industry, but also find a place in many manufacturing sectors, chemical storage, and even residential uses.
