The valve body can be supplied wafer, lugged, flanged or butt-welding ends type in a wide range of sizes (from 2' to 112'). Casted or electric welded execution, the body is supplied in the following materials; carbon steel, stainless steel, bronze or aluminium /bronze duplex, superduplex, monel as standard.
The seal ring in synthetic material ensures a perfect bubble-tight shut-off at the maximum rated differential pressure.
The design of the ITV sealing allows replacement of the seat ring without removing the disc; in addition, this operation does not require an expert. For special uses (food-stuffs, aggressive or corrosive fluids etc.) a special sealing can be applied, which, as may be seen from the illustration, is composed of an outer teflon sheath which comes into contact with the fluid, and an inner elastic ring, performing the sealing action.
