The SC damper is composed of a blade which turns on a shaft located on one side (like a gate). The ends are joined to the pipes via flanges. Normally, the SC damper is supplied as one piece, except in those applications in which the dimensions of the equipmentrequire special transport.
The body of the SC damper is machine welded and can be made of different materials. The standard construction sizes range from 150×150 mm (minimum) to 3000×3000 mm although larger sizes are available on request. The blade is made flat, with reinforcing ribs and is supported on two semi‐shafts. The flat blade system is sufficiently rigid for the working pressures of these valves and they do not produce significant load losses.
