Linatex LinaValve DV

Linatex LinaValve DV

Linatex LinaValve DV is a pneumatic or hydraulic operated, enclosed and Linatex premium rubber lined pinch valve designed for effective control of abrasive and corrosive flow media. When coupled with the proper instrumentation and pressure application, the LinaValve DV provides both efficient modulating flow control and drip tight shut off. The LinaValve DV is suited for harsh, highly abrasive flow control applications in liquid-solid slurry and gas-solid pneumatic conveying services where long valve life and low maintenance are desired. With its unique Delta shape and subsequent low pressure differential to close, a minimum of closing medium is used which results in lower operating costs.


  • Linatex anti-abrasive premium red rubber is the standard liner material.
  • Pneumatic or hydraulic medium can be used to operate the valve.
  • Low profile Delta design reduces closing forces and lessens stress and fatigue on the liners.
  • Twin valve liners fold toward one another creating a reliable seal even when closing on trapped particles.
  • Valve half liners allow for replacing one half at a time.
  • Liner’s reinforced rubber flanges provide a reliable seal when the valve is bolted up to a standard flat face flange.
  • Closed body design provides a secondary containment in the event of a liner failure.
  • Valve can be operated in any position.
  • Elastomer liner reduces piping vibration andwater hammer.
