API 6A Gate Valve
Gate Valve is used to open or close the pipeline. According to the structure, the gate valves is distributed into rising or non-rising stem gate valve. According to the mode of operation, it is distributed into manual or hydraulic etc. The gate valve is used for drilling fluid manifold, choke manifold, kill manifold and Christmas tree etc.
The plate gate valve is the main component of the Christmas tree, the tubing head, the casing head and the manifolds. It is one of the major products manufactured by deenpu. In recent years, by making use of advanced technology both at home and aboard, deenpu has developed an innovated quite a few new designs of the value in terms of products structure and material selection. The products are all manufactured, checked and accepted as per API Spec 6A standard.
