Closed Body CBV

CBV Enclosed Pinch Valve

The CBV model pinch valve is a heavy-duty enclosed construction full bore valve that employs elastomer sleeves for flow shut-off and control in applications with abrasive and corrosive slurries. The sleeve is the only part in contact with the media, no other mechanical parts are required, and it is a maintenance free part. The CBV pinch valve is mainly used in industries such as:

• Mining
• Chemical plants
• Pulp and paper
• Power plants
• Wastewater treatment
• Cement and ceramic
• Etc.
