Cast Steel Trunnion mounted ball valves allow easy and smooth operation at high line pressure. Carefully aligned bearings assist low torque operation. The ball is fixed in position but free to turn. All casted Trunnion Ball valves manufactured by XDV are with reliable high quality castings and fire safe design certified according to BS 6755, API607&API 6FA.Meet all applicable ASME standards. Cast Steel Trunnion Ball Valves Manufactured by XDV are available in types of Two Piece Split Body & Three Piece Bolted Body Designed and manufactured to the most updated international standards APl 6D, ASME B16.34, BS 5351 or equivalents. With standard features of Fire Safe, Anti-static and Stem Blow-out Proof.

XDV top entry ball valves are designed, manufactured and tested in accordance with API 6D and ASME B16.34. Can meet API 607 sixth edition and API 6FA third edition specification requirements. The valve size range is from 2 inch to 48 inch, pressure rating is from 150LB to 2500LB. Top entry ball valves are capable for on line maintenance, there may replace or repair the ball, seat or soft seals after strip the cover, so XDV top entry ball valves have been widely used for oil & gas pipeline.

XDV Full welded ball valves are intended to be fitted as stop/shutoff valves in water and gas-supply systems, in the heat-power engineering, housing and communal services as well as in the process lines at chemical and oi-refining plants, at pulp-and paper milks production facilities. XDV Full Weld Ball Valve Design Features ”Seamless Carbon steel or stainless Steel Body: All welded ball valve body is compact and streamline for maximum strength and minimum weight. ”stainless Steel Ball: The stainless steel ball is produced to extremely tight tolerances, and ground to within microns of perfect roundness to assure smooth operations and a tight seal. ”Optional Locking Device With Position Indicator: Instantly readable locking device that shows the valve operating position. ”Stem Bearings: These bearings are produced from an electrically conductive material that provides a safety grounded stem to eliminate static build-up and potential arcing. ”SEAT SEALS: The special 25% carbonized PTFE (Teflon)(G-453)seals tightly, yet allows easy. low-torque, quarter-turn operation. ”STAINLESS LABELS: Every label is permanently stamped, color coded with traceable serial numbers for each valve ”SEAT QUALITY FEATURES: Do not absorb water, and does not expand Chemical resistant, High friction characteristics Good temperature stability, Tested and approved up to 250℃

With all advantages of Trunnion Mounted Ball valves, XDV Forged steel Line are available in types of Two Piece Split Body & Three Piece Bolted Body. The forging material can ensure sufficient rigidity and strength under maximum rated operation pressure. Without inherent flaw of cast Enough wall thickness of separate body and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient to bear the stress of pipe. The internal parts of valve are carefully designed and selected to ensure reliability under all kinds of work conditions.
