High-performance valve 1200 series

butterflymanualelectrically-operated

The high performance butterfly valve is available in sizes 2" - 24" with a one piece wafer or lug body. Body materials include stainless steel and carbon steel and sealing standards in conformance with ASME 150/300 class rating. Top flange is drilled to ISO 5211 standards and utilize a flexible lip seal concept when disc closes. The true choice in a high performance butterfly valve need - available manual or actuated. Series 1200 (High Performance Stainless Steel Body, Class 150/300) The high performance double eccentric butterfly valve is a great solution for any industrial need. Made from top quality materials and with a long lasting design that's made to fight corrosion and vibration. Both wafer and lug butterfly valve designs offer bi-directional sealing as a standard in conformance with ASME. Butterfly valves are available for saturated steam at 200PSI and 450PSI with a tight shut off vacuum to 2x10(2). The unique seat design utilizes a flexible lip seal concept When the disc closes, this action causes a slight deflection in the seat, energizing the seat. During this energized position, the seat has a stored energy force constantly pushing against the disc. In addition to this "energized" force, when pressure is on the insert side, the pressure pushes under the lip which further amplifies the sealing force between the disc and the seat. High Performance Butterfly Valve Series The offset disc produces a cam-like action, pulling the disc from the seat. This action reduces seat wear and eliminates seat deformation when the disc is in open position.
