TRUNNION MOUNTED BALL VALVE
SEV Trunnion mounted ball valve is developed by our engineering technicians by using their more than 30 years experience in design and manufacture of valve and adopting the international state-of-the-art technology, which is mainly used for the long transfer pipe lines of petrol, natural gas and paste, and various industries. In view of the unique features of valves for long transfer pipes. due consideration has been given to their pipe stress resistance, safety and weather resistance, etc. in the design. The design of sealing and structure is our sole property. Various operation modes are available including manual, worm gear-driven, pneumatic-driven, pneumatic-hydraulic driven, electrically-hydraulic driven, computer controlled, as well as various special control modes.
