摘要： The present invention provides a gate valve assembly having a valve body (201) with a channel extending from a distal end to a proximal end, a gate configured to be moved from a first position to a second position, the second position being when the gate is positioned in the channel of the valve body between the distal end and the proximal end of the valve body. A seat insert (202, 222) is also provided to be threaded into a pocked of the valve body and a seat (208) is configured to be positioned within the seat insert. A seal (210) is adapted within a groove of the seat insert positioned between the valve body and the seat insert, wherein the seal is a fixed static seal providing no gaps and/or spaces between the seat insert and the valve body allowing no debris to corrupt the seals.

摘要： An embodiment includes a gate valve comprising: a valve body including a cavity coupled to a channel having proximal and distal portions; a gate to seal and unseal the channel; proximal and distal seats adjacent the gate; wherein (a) the proximal seat traverses towards the gate and stops at a first position when the gate is closing and the proximal channel portion is more highly pressurized than the cavity, and (b) the distal seat slides away from the gate and stops at a second position when the gate is closing and the cavity is more heavily pressurized than the distal channel portion. Other embodiments are described herein.
