Linatex Linatex LinaValve BT

Linatex LinaValve BT

Linatex LinaValve BT is a handwheel operated enclosed pinch valve designed for effective control of abrasive and corrosive flow media. With its centerline close, dual action pinch mechanism the LinaValve BT can attain both efficient modulating control and drip tight closure. Lined with Linatex premium natural rubber, the LinaValve BT is well suited for harsh, highly abrasive flow control applications in liquidsolid slurry and gas-solid pneumatic onveying services. The abrasive-resistant rubber lining contributes to the valve’s long wear life and low maintenance costs.


  • Linatex anti-abrasive premium red rubber is the standard sleeve lining
  • Full bore/full flow design results in low friction lossand high flow capacity
  • Center pinch design for predictable linear flow performance, reduced turbulence and longer sleeve wear life
  • Closed body design provides a secondary containment in the event of a sleeve failure
  • Low force manual handwheel actuation
  • Short valve length accommodates tight installation requirements
  • One piece sleeve protects operating mechanism and body parts from exposure to process.
  • High flexibility sleeve design reduces closing forces, improves recovery to full open position and ensures drip tight closure.
  • Sleeve’s full face flanges provide a reliable seal when the valve is bolted up to a standard flat face flange.
  • Elastomer sleeve reduces piping vibration andwater hammer.
