A105 forged steel fixed ball hard seal ball valves are intended for industrial services where a forged A105 body and a fixed (trunnion-supported) ball with metal / hard sealing are specified. Jiangsu Tekron Flow Control Valve Co., Ltd. supplies this product under the Tekron / Trekre brand series. Exact seat pair materials, temperature limits and leakage acceptance shall follow the technical agreement and test documents.
Fixed ball construction
This product is described as a fixed / trunnion-mounted ball valve. The ball is supported by the stem/trunnion structure rather than relying on free ball displacement for sealing. During operation the ball rotates with the stem between open and closed positions. This differs from a free-ball-seat design in which the ball may move slightly under fluid pressure and press against the downstream seat.
Hard / metal seating (neutral)
Hard-seated / metal-seated construction is indicated by the product title. Specific sealing-pair materials, overlays and temperature capability must be confirmed from technical documents and order requirements. Do not assume a particular metal grade or leakage class without documentation.
Sealing performance
Sealing performance should be confirmed according to the valve design, applicable test standard and order requirements.
Selection
Match size, pressure rating, ends, seat materials, packing and drive (manual, worm gear, pneumatic or electric) to the process conditions. Jiangsu Tekron Flow Control Valve Co., Ltd. can assist with configuration; final parameters follow the order technical agreement, nameplate and test report.
