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 through.
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.

Characteristics
1. Adopt unique rubber formula, good ability of corrosion resistance, wear resistance and pressure resistance.
2. Valve replacement parts rubber hose. Simply replace the hose, the valve is in good as new.
3. Bubble tight seal. Mechanical parts of the valve are protected, only rubber in contact with fluid
4. Full bore design provide good flow through ability. There is not room for dust and particles to accumulate.
5. Different rubber hose will be Selected upon different fluid. Wide applications.
6.Working pressure is less than 1.0 MPa, in the presence of negative pressure in the process use special manufacture of rubber hose in the system.
