The Paddle Bind is usually known as Spade, Line Blind. The Paddle Blind is made from a round piece of different type of material, with a handle furnished in a different form, according to the dimensional standard. The Flanges are usually raised face, flat face or ring type and are often defined by ASME standards. The Paddle Blind is inserted between two Flanges (with a Gasket on each side) to stop the fluid. It can be used for example for maintenance of the line or the change of production, and it may have the function of firestop.
