進口高溫高壓承插焊針型閥，截止閥結構特征 Structure characteristics

產品的設計符合ASME VIII，ANSI B16.34/B16.5B31.3 和API6D的相關要求retz品牌  The product design shall conform to ASME VIII, ANSI B16.34/B16.5B31.3 and API6D

不旋轉閥芯，以確保壓力關閉的緊密性不旋轉閥桿承受超高壓和超高溫  Do not rotate the valve element to ensure the tightness of pressure closing. Do not rotate the valve stem to withstand ultra-high pressure and ultra-high temperature

填料位于閥桿的下方，以隔絕螺紋與介質的接觸  The packing is located below the valve stem to isolate the contact between the thread and the medium

非旋轉閥桿  Without rotating the valve stem
