A gate valve includes a floating gate valve seat 27 that effects a seal between a gate 17 of a gate valve and a gate valve body 13. The gate valve seat 27 has a spring member 43 with a cylindrical portion 44 secured to the gate valve seat 27. The spring member 43 has a leg 45 that exerts a spring force against the gate valve body 13 to maintain a seal between the floating gate valve seat 27 and the gate 17. A metal-Âto-metal seal 41 seals between the cylindrical portion 44 of the spring member 43 and a cylindrical portion of the gate valve seat 27. |
