1) Made from forging or specially smelted low alloy steel
2) Wellhead assembly

1,Design and manufacture are carried out in accordance with Standard SY5156 and API Spec.6A;
2,Non-rising stem gate valve with switch indicator;
3,To ensure wellhead safety, all Pressurized parts and flanges on the wellhead equipment are made of high grade alloy steel by press forging which are also subjest to non-destructive tets and heat treatment, achieving excellent sulfide-resistant performance;
4,Special lubricated device used to ensure smooth lubrication between ram and valve seat, and also prevent sealant from losing;
5,Reliable in performance and durable in usage in usage due to its small on-offtorque
