Product Description

Electric double eccentric butterfly valves have the structure of 3D eccentric metal sealed, whose seal mode is metal-to-metal, also can be changed into the other seal modes such as the metal seal ring to the metal, and the stainless steel plate seal ring or the graphite composite plate seal ring to the metal. This 3D eccentric metal seal butterfly valve with high performance is a device to regulate and cut off the medium of those piping in petroleum, chemical, power, metallurgy and city heat supply system.

Welded Bed Plate For Flanges Of Ship Pipe
The flange welded single-sided seat plate is mainly installed on the top, side wall and bottom of the cabin or cabinet as the entrance and exit of the cabin or cabinet. Valves, accessories or pipes can be installed directly on the single-sided seat plate.
Flange welded single-sided seat plate is suitable for seawater, fresh water, oil, air and steam pipelines below 300 °C. The commonly used nominal diameter is 15~150 mm, and the nominal pressure is lower than 1.6 MPa. The shape of the single-sided seat plate is similar to the corresponding lap-welded Steel Flange.
Flange welded double-sided seat plates are generally used when pipelines pass through decks and tanks, and the two sides of the seat plate are respectively connected to valves, accessories or pipes.
Compared with the single-sided seat plate, the double-sided seat plate has an extra shoulder and double-sided mounting stud bolts. The outer diameter of the shoulder is 10~20 mm larger than that of the corresponding flange, and the thickness of the shoulder is 6~12 mm.
Its scope of application and other structural dimensions are basically the same as those of the single-sided seat plate.
The manufacturing and installation methods of the flange-welded double-sided seat plate are basically the same as the single-sided seat plate, but when the screw holes are drawn, the positions of the upper and lower screw holes of the seat plate must be staggered from each other and must not overlap; deck or bulkhead The diameter of the hole on the top is 2~3 mm larger than the diameter of the seat plate.
