Product Overview

A three piece ball valve with threaded ends and a locking lever is designed for reliable shut-off and easy in-line maintenance in industrial piping systems. Its split-body construction allows the centre section to be removed for cleaning or seal replacement without cutting the pipe, while the locking lever provides added safety by preventing accidental operation. Commonly supplied in stainless steel, this valve type suits applications requiring dependable flow control, secure operation, and long service life under pressure and temperature variations.

Product Features

  • Three-piece body design allows the centre section to be removed for maintenance without dismantling the pipeline
  • Threaded end connections enable quick installation and easy replacement in existing systems
  • Locking lever handle prevents accidental valve operation and improves on-site safety
  • Full port design supports smooth flow with minimal pressure drop
  • Stainless steel construction offers excellent corrosion resistance and long service life
  • Suitable for high-pressure and temperature service in industrial and process applications
