API 6D Gate Valve
The pipeline API 6D gate valve is designed to satisfy the long-term transportation service of crude oil and natural gas. It meets the requirements of API 6D specification, has two-way blocking and relief functions, and can be used for two-way fluid shutoff. Two main series are provided: soft-sealed single-level gate series and hard-sealed double-level gate series.
We produces the following gate valves
API 6D OS&Y Gate Valve,
API 6D Through conduit gate valve
API 6D pipeline gate valve
Double Block & Bleed Gate Valve
