Pinch valve is a modified version of laboratory pinchcock. A rubber sleeve is protected under a metalic casing – i.e. CAST IRON, CAST STEEL – WCB, STAINLESS STEEL, ALLUMINIUM. The fluid passing through do not come in contact with either body covering or any other metal parts of the valve except the sleeve. Hence the body and other metal parts are almost permanently not subjected to the corrosive action of the fluid. The flow through the valve is straight and full as that of a pipeline, when the valve is fully open. Further, the collar of the sleeve eliminates gasket. The valve is simple hand wheel operated of rising wheel type. Therefore the operation of the valve is just simple as other wheel operated valve. Fine threading in the spindle permits us the desired controlling. Thus the valve offers positive & smooth flow with fine/desired control over flowing media.   APPLICATIONS Chemicals, Alkaline Mixtures Acids, Slurries & intermediates, Liquid Foods, Viscous fluids, Sludge’s, Granules Dry Suspension Powder Collectors Gases Pulps Vacuum Sewage Plants Thermal Power Stations Water Containing Ash.

An Air pinch valve is a pinch valve. Air or liquid pressure is inserted in the cavity of AIR PINCH VALVE - at the control inlet collapses the internal rubber sleeve to provide immediate and positive shut-off. The rubber sleeve closes completely, even on large particulate matter, abrasive and corrosive materials. When open, the sleeve allows full, unobstructed flow with little turbulence. Air pinch valve sleeves can be easily and economically replaced when they wear out. SIZES AVAILABLE SCREWED END 15, 25,40 & 50 MM FLANGE END 15, 25, 40, 50, 75 & 100MM SLEEVE AVAILABLE - NEOPRENE, NATURAL, HYPALONE, EPDM, VITON, SPECIAL ABRASSION RESISTANT PRESSURE UPTO 6 BAR POSITIVE OPERATION Air pinch valves give fast & positive shut-off of most industrial materials, liquids, and dry flowable materials. Air pinch™ pinch valves will close tightly on suspended particulate materials in liquids. Even highly viscous materials are no problem. Air pinch valves are versatile because of their unique flow-through design. It provides fast & smooth rapid operation, 100% full way, unobstructed flow, and complete close design. It can be mounted in any position or direction, & also works perfect even in fully submerged condition. ECONOMICAL DESIGN Air pinch valve housings are light weight and well suitable to use where heavy valves not required or won’t work. investment casting in wcb/cast steel, or investment casting cast stainless steel. No moving parts hence a sturdy long lasting valve at an economical fair price. PINCH VALVE OPERATION / OPERATION PRESSURES Operating pressures for controlled material vary depending on sleeve elastomer and valve size, and can range from a moderate vacuum (up to 26" Hg) to a maximum of 90 psi when controlling with air. Required control pressure is normally 20 to 40 psi greater than the material pressure. Use of excessive actuation pressure (air or liquid) than that which results in complete valve closure will impact sleeve life. Use of actuation pressure above 90 psi is not recommended.
