Advantages of the Control Seal ™ Design. 

  Friction free opening and closing, increasing the lifetime of the valve. 

  Corrosion and wear resistant materials are used on the closure members. 

  Bottom and top access for inline inspection and maintenance. 

  Adjustable stem packing while the valve is in service. 

  All valves are executed with a backseat, which gives the possibility to renew stem packing under pressure. 

  Non lubricated seal.

   Pressure independent sealing. 

  No coupling cam in the stem construction. 

  Topworks according to ISO 5210
