KST - Ceramic-lined floating ball valve

The CeraValve type KST is a ceramic-lined ball valve suitable for corrosive media with abrasive solids content. The high quality ceramic internal parts provide excellent wear resistance. The valve can operate as an On/Off Valve as well as a Throttling Control Valve.

The CeraValve type KST has a floating ball design. There is a defined clearance between the ball and the fixed upstream and downstream seats. The ball is seated against the downstream seat by the differential pressure of the fluid through the valve. The valve housing and flanges are made of 304 Stainless Steel with the option of several other construction materials. Other ceramic materials are also available for selection aside from the standard Zirconia ball and Alumina seats. The CeraValve type KST-HT is also available for high temperature applications.

These valves can be equipped with a hand lever or with SAMSON GROUP actuators and valve accessories such as positioners, limit switches, and solenoid valves.
