Product Overview

A three piece threaded ball valve is designed for reliable shut-off and easy in-line maintenance in demanding piping systems. Its modular three-piece body allows the centre section to be removed for cleaning or seal replacement without disconnecting the threaded pipe connections, helping to reduce downtime. Commonly supplied in 304 or 316 stainless steel with female NPT threads, this valve offers full port flow, strong pressure performance, and dependable sealing for industrial, chemical, water, and process applications.

Product Features

  • Three-piece body design allows in-line maintenance without removing the valve from the pipe
  • Female threaded (NPT) ends for quick installation and easy replacement
  • Full port (full bore) design for minimal pressure drop and efficient flow
  • Available in 304 or 316 stainless steel for excellent corrosion resistance
  • PTFE or R-PTFE seats for reliable sealing across a wide temperature range
  • Suitable for high-pressure service, commonly rated up to 1000 WOG
