THE HEART OF THE Linatex VALVE
The heart of the Linatex pinch valve is the unique sleeve lined with tough
abrasion and corrosion resistant Linatex (Other synthetic and natural rubbers are also
available). The simple-to-replace pinch sleeve is the only valve part in contact with the
fluid. No packing to leak, no metal to wear or corrode.
The full bore opening of the design virtually eliminates friction losses and with
double action closing feature assures maximum sleeve life. The resilience of the lining
ensures a drip tight closure on solid particles.
The "T" type sleeve design extends the pinch valve range of throttling
control while providing long wear life.
