Full welded ball valve is 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 oil-refining plants, at pulp-and paper milks production facilities.
Full welded 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℃
