Open Body Pinch Valv

Pinch valves, offered by our company, are the modified version of laboratory pinchcock in which rubber sleeve is protected under the casting made of cast iron. The main advantage of Pneumatic Pinch Valves is that the fluid passing from it does not come in contact with its metal parts except the sleeve. This property makes it corrosion resistive against the action of various fluids. Open Body Pinch Valves assure the smooth flow of water like pipeline and their collar sleeve eliminates gasket. Pinch valve is user friendly and can be operated easily as compared to other wheel operated valves. This valve allows positive control over flowing media because of its in between stoppage that gives desired throttling. These pinch valves are extensively used for handling corrosive slurry, liquid with solid suspensions, abrasive media, and many others. We offer pinch valve in best application range with flange as per BS, DIN, ASA & IS dimensions, and ranging between 15mm to 300mm. We are known widely as one of the proficient Pinch Valves Exporters and Suppliers. General Features & Highlights Seat Less & Glandless ValvesField Replicable Elastomer Sleeve.Elastomer Sleeve Having Four Reinforced LugsFlanged Ends & Drilled to Din, Ansi, Bs-10, Is, Etc.this Valve Incorporates allthe Design Modifications Based On Our Experience & is of Study Construction to Handle Abrasive Corrosive Media. BRIEF DETAILS OF PINCH VALVE Pinch Valve is a Seat less & Glandless valve.Pinch valve is a modified version of laboratory pinchcock. A rubber sleeve is protected under a cast iron casting.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.The in-between stoppage will allow the desired throttling. Thus the valve offers positive control over flowing media. Applications Pinch valve finds its best application in handling corrosive slurry, abrasive media, liquid with solid suspensions and many others, which are difficult to handle with seat valve. Range The flange of the pinch valve can be supplied in accordance to BS, DIN, ASA & IS dimensions The range for the valve is from 15 mm TO 300 mm. Actuation The valve can be supplied with Electrical and pneumatic actuation. Operating Manual OF PINCH VALVE THE PINCH VALVE is a modified version of the laboratory pinchcock. A rubber sleeve is protected under a Cast iron or Aluminum split body casting. The valve is a simple hand wheel operated of rising wheel type. The operation of the valve is same as other hand wheel operated valve, it closes when moved in clockwise direction and opens when moved in anticlockwise direction. The in-between stoppage will allow the desired throttling. Thus the valve offers positive control over flowing media. The flow through the valve is same as that of a pipeline, when the valve is in fully opened condition. Further, the rubber sleeve eliminates the need of a gasket. PRELIMINARY PRECAUTION On receipt of the valve please check the position of the valve, as it is advisable to keep the valve in fully opened condition. Also check the position of the travel limit nut, if found loose then tighten the set screw of the nut. INSTALLATION The valve can be installed without any gasket unless it is required for some specific purpose. Tighten the nut of the flanges evenly & equally, but avoid too much tightening. After installation check the free movement of the upper & lower pinching bar by opening & closing the valve. The valve is then ready for the service it is installed for. MAINTENANCE If the valve is found leaking through the seat after sometime even though in fully closed condition, then set the travel limit nut by just taking it 1 or 2 threads above & then tighten. This will allow more room for traveling of rubber sleeve & ensure the valve to zero leakage. This problem sometimes occurs when the sleeve is slightly worn out, when used under abrasive condition. Further, The Rubber sleeve of the valve up to 2” (50mm) have a single lug on either side and it goes into the hollow passage of the pinching bar where it is fixed with the lug clamping screws. In the higher sizes above 2” the sleeves have two lugs on either sides and is fitted overlapping the pinching bar. DISMANTLING THE VALVE & REPLACING THE RUBBER SLEEVE When the rubber sleeve is ruptured or totally worn out then it is to be replaced with a new one. In this case first dismantle the valve by following the instructions. Remove the hand wheel.Open the Tie Bar nuts.Disconnect the spindle from the Horseshoe connection and remove it completely with the bridge.REMEMBER not to temper the set screw of the yoke bush, unless if required it should be completely tight.Open out the nuts & bolts of the split body of the valve.Remove the screw of the lugs from both the pinching bars.Now fit the new rubber sleeve & reverse the operation to assemble the complete valve. NOTE It is advisable to keep a spare rubber sleeve for maintenance purpose, considering the self life of the Rubber as six months when packed & stored in dark. The Pinch valves should be stored in fully open condition only. We also offer complete spares of the valves, but request you to place your order a week in
