Fully Welded Ball Valves
BÖHMER fully welded ball valves meet the requirements of the most common national and international standards.
When fire safe certification is required, BÖHMER can produce a range of valves to API 6FA, API 607 and BS 6755 P 2.
TRUNNION MOUNTED BALL
The standard design of BÖHMER ball valves provides a trunnion mounted ball for pressure class ANSI150 starting at 6 inch and ANSI300 and above at 3 inch size. The maintenance-free bearings for stem and trunnion are self-lubricating, thus assuring a lower torque especially for high pressure ratings.
When required, the ball valve design includes an electric conductive connection between the internal parts of the ball valve and the body providing the anti-static function.
The sealing of the stem to the atmosphere is achieved by up to three independent sealing systems. The stem sealing design ensures the anti-blow-out function. Some valves can be produced with a design of the stem assembly, so the seals are replaceable under full pressure in either open or closed position.
As an option, BÖHMER ball valves can be delivered with an additional emergency sealing injection for the seat-rings and/or stem sealing.
