Y Type SS304 wholly SS , angle seat valves are designed to be used for a long period of time without any problems to turn on and later off the flow of steam and aggressive chemicals in the installations . Owing to that bonnet is made of SS304 and all other components are made of SS 316 , it has a high constructional resistance and at the same time , it can operate without any risk of corrosion in the media that includes steam and chemicals ( asidic – caustic media ) . As sealing components are made of alloyed PTFE , these components do not get affected by any chemicals .
