Note:


  • Above structure, seat is metal sealing, PTFE soft sealing is VI grade as option. Also can provide stillate hard sealing. As per actual working temperature, we may choose proper bolt & nut accordingly.

  • PTFE V type stem packing is with graphite, the working temperature can be higher than 232℃(450 F)

  • The common body material is WCB and S.S, can apply with other high corrosion resistance alloy material.
