Forged steel bellow sealed valves are designed to eliminate valve leakage creating hermetic sealing and manufactured with hydro-formed multi-fly bellows, welded to the stem and bonnet. Conventional gland packing is replaced by a bellow cartridge ensuring emission free use. Wall Thickness and General Designs are API 602 for forged gate valves/ ASME B 16.34/BS 5352 for forged globe valves/ API600 for cast valves. Cycle Life Test is performed under the max pressure condition. Stem backseat and stem packing ensure the perfect sealing when a bellows is damaged. And Stellite 6 faced both seat and wedge/disc to prevent seizing and galling.
