Trunnion Ball Valve
Trunnion mounted ball valves are custom made with 2-piece or 3-piece bodies per API 6D specifications. These trunnion ball valves are available with soft seats and metal seats. Metal bases designed with ENP or other special coatings to meet abrasive or corrosive requirements.
API 6D Ball Valve
The API 6D ball valve is designed in accordance with API 6D, the ball valve is connected by bolts, the seat ring is trunnion mounted, and the spring is loaded to ensure contact with the ball, even if the pressure difference between the cavity and the downstream closure is low.
Integral DBB Valve
Integrated DBB valve integrates dual sealing and relief functions to provide reliable double isolation protection in high-risk scenarios such as petroleum and chemical industries. Its design must strictly comply with standards such as API 6D and API 608 to meet the needs of high-pressure and corrosive media.
