Manual Forged Stainless Steel Carbon Steel Self Sealing Socket Welding Gate Valve

The main features of self-sealing gate valve are good sealing performance, small flow resistance, light switch, good cutting performance and wear resistance. Its sealing performance mainly depends on the metal to metal seal between the seat and the disc, so that the medium can not leak, suitable for high temperature and high pressure and strong corrosive media piping system.
