B.UHV Series

UHV Series valves are toggle action, linear travel gate valves. The gate carriage moves in the valvebody on a set of wheels, moved back and forth by a manual or pneumatically actuated valve stem which passes through a metal bellows.To close the valve, the carriage moves forward on wheels until it reaches the end of the valve case.When the carriage stops, the toggle linkage continues to travel and extend. The gate does not move forward, only upward toward the port seal surface. There is no abrasion or damage to the O-ring. The gate moves up to the port into its sealing position. The O-ring is compressed, making a leak-tight seal. The toggle linkage continues to move forward until the toggle knee passes centerand locks, providing positive closure protection in the event control power, or air pressure, is lost.
