結構特點及用途:
手動球閥手動法蘭球閥它具有旋轉 90 度的動作，旋塞體為球體，有圓形通孔或通道通過其軸線。球閥在管路中主要用來做切斷、分配和改變介質的流動方向，它只需要用旋轉 90 度的操作和很小的轉動力矩就能關閉嚴密。球閥宜做開關、切斷閥使用。
重要特點:
◎ 2片式浮動球閥
◎ 防吹出，防靜電閥桿
◎ 多種法蘭標準
◎ PN25-PN40,150LB,300LB 標準
◎ 鑄造手柄
◎ 帶防火設計 ( 定制 )
設計/檢測標準:
設計標準: GB/T 12237 ASME B16.34
結構長度: GB/T 12221 ASME B16.1
法蘭標準: HG/T 20592 ASME B16.5
測試標準: BG/T 13927 API598
