Gate valves are with an elastomer lined wedge. The wedge is fully vulcanized with drinking water approved EPDM rubber compound. They are especially used in drinking water application. Long centric wedge guided for minimal operating moments. Maintenance-free due to medium-free spindle bearing and permanent lubrication. Triple seal valves for long service-life and absolute tightness. Back seal for replacement of the stem parts under operating pressure
Gate valves for industrial application are made of Carbon Steel or Stainless Steel. Die forged body and bonnet. Outside crew and yoke. Available with flange, socket and butt weld ends. Suitable for high temperature and high pressure applications.
