Butterfly Valves are used in powder or liquid handling purposes to isolate or regulate the circulation product. The closing mechanism is a disk that rotates, thereby permitting or preventing the circulation of material. The “butterfly valve” is a metallic disc (stainless steel out there) mounted on a rod. When the valve is closed, the disc is turned so that it fully blocks off the passageway. When the valve is totally open, the disc is rotated a quarter turn so that it allows an virtually unrestricted passage of the product or liquid. Bray Butterfly Valves are ideal for unloading and discharging material from containers, hoppers or silos containing supplies in powder or granular in powder handling applications. Carolina Materials Applied sciences provides 14 different models of the Butterfly Gate Valve, together with butterfly valves which may be opened incrementally to permit throttle circulation. There are three most important categories: Resilient Seated, Double Offset, and Triple Offset.

Classification, verification, danger administration, and technical advisory to the maritime trade on security, enhanced efficiency, fuel effectivity, and so forth.

Robert Bochenski, the upkeep manager at Emerald Pointe, compares the “Thunder Bay” type of wave pool to a large bathroom. The pump system attracts water from the return canal into the gathering reservoir in the same manner that a rest room attracts water from the water line into its tank. When the water level within the reservoir is high enough, the system opens up the release valves at the underside of the reservoir. This is like flushing a bathroom: It dumps the entire collected water into the pool, creating the wave.

Audi’s Steppenwolf concept vehicle, which was unveiled at the 2000 Paris Auto Show, made its North American debut at the 2001 NAIAS in Detroit. The Steppenwolf is one other of the many crossover SUV ideas being introduced at this year’s show. It is designed to be an off-road automobile that is equally at home in the Australian outback as it’s on fifth Avenue in Manhattan.
