The Beaver three-piece trunnion ball valve features a fixed ball and two independent floating seats which assure bidirectional sealing. When the ball is closed and both seats are simultaneously sealed, the cavity can be relieved of entrapped pressure.

The seats can guarantee full sealing as there’s zero differential pressure to the valve’s maximum rated pressure. The seat design and trunnion-mounted ball also minimise the torque needed to operate the valve. The API 607-compliant firesafe valve is available as full or reduced bore in Class 150, 300, 600, 900, and 1500.
