遠東旋塞閥有壓力平衡式倒裝油密封旋塞閥，提升式旋塞閥，卡套式旋塞閥，三通四通旋塞閥。旋塞閥有一 個或者兩個沖刷面，這里只有個別的類型，如果需要其它，與我們。旋塞閥根據ANSI設計制造，廣泛應用于諸如石油，化工，肥料，電力等行業(yè)。壓力范圍 150Lb-1500Lb，工作繭自縛溫度為-29℃~550℃。連接型式有法蘭和對焊。驅動方式：手輪、蝸輪、管套。
⊙設計范圍
遠高鑄鋼旋塞閥符合：API599，API6D，ANSIB1 6.34 
閥門檢驗：API598
 標識：MSS-SP-25
⊙應用標準
·設計標準 Design and Manufacture: API 599, API 6D
·結構長度 Face to face（end to end）: ANSI B 16.10
·連接法蘭 Flanged connection:  ANSI B16.5
·試驗和檢驗 Test and inspection: API 598, API 6D
⊙主要結構特點
栓接閥蓋，旋轉90度開關。它的密封性是通過卡套四周的密封面來實現的。*的360°金屬唇邊保護固定卡套。閥門沒有空腔給介質積聚。金屬唇邊在旋塞轉時提供自潔的作用，適合于粘稠和易結垢的工況?？梢噪p向流通。

栓接閥蓋，提升式旋塞設計，它的密封性是通過閥片四周的 密封圈來實現的。*的燕尾槽保護和固定密封圈。雙向流動，安裝使用更方便。

Bolt bonnet OS&Y lifting一round plug, Its sealing is realized by the sealing rings around the valve disc. It has unique protection of swallow tailed sink and fixed sealing rings. Double direction.

⊙工作原理 Principle of opening and closing of the valve                                                                     

當閥門全開的狀態(tài)下，塞子的通道興閥體的通道對齊，能保證理想的zui低壓力降.當轉動手輪，塞片轉動9。度，當繼續(xù)轉動手輪，塞子將會下壓，使閥門向兩側張開，閥片將緊緊的壓在閥座上，使閥門關閉;當手輪向反方向轉動時，首先使塞子向上運動.使閥片于閥座脫離，繼續(xù)轉動手輪，使塞子帶動閥片90度zui后塞子的通道于閥體的通道對齊，使閥門處于全開的狀態(tài)。

When the valve is fully opened, the channel of plug is in alignment with the channel of valve body, which can ensure ideal and lowest desc rea seon pressure, When the hand wheel is turned, the plug will rotate toward the closing direction, and make the same time draft the rotation of valve seat will he Se- parated; if the hand wheel is turned inversely, first of all the plug will move upward, and the valve disc is turned by 90 degree driven by the plug, and finally the channel of plug will be in alignment with the channel of valve body, so that valve is be fully opened.
