Zero Leakage Red Valve Type Enhanced NR Sleeve Pinch Valves For
About Pinch Valve
The sealing in pinch valves is achieved throttling the flexible
tube of the valve named elastic sleeve which is the only part in
contact with the medium.
Pinch valves are suitable for handling slurries and solids in
suspension, avoiding contact with the valve mechanism and any
contamination towards or from the environment.
Generally, the pinch valve is limited to work at low pressures.
Pinch valves can be mechanically or pressure actuated. it is
advised to close tightly the valve to prevent erosion of the
flexible tube by the effect of leakage flow.
In pressure actuated pinch valves, the pressure is uniformly
distributed over the external side of the flexible tub.
As advantage over the mechanically actuated valves, the pass
section is always circular and then bigger particles can go
But pressure actuated pinch valves can not be 100% closed and can
not be manually controlled since there is a dependency on the flow
pressure, this can be resolve with a pressure regulator.
The flexible tube is made of elastomer, usually reinforced.
Material selection should be done according to a corrosion-strength
commitment since the elastomer strength properties can be reduced
by the attack of the corrosive fluid. Fatigue limit of the material
must fit on-off valve cycling.
