INFORMATIONS ON 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 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.
- Size 15MM TO 400MM
- 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.

Operating Manual OF PINCH VALVE
A rubber sleeve is protected under a CAST IRON, CAST STEEL – WCB, STAINLESS STEEL, ALLUMINIUM, 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.
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 both sides and are fitted overlapping the pinching bar.
DISMANTLING THE VALVE & REPLACING THE RUBBER SLEEVE
- Open the Tie Bar nuts
- Remove the spindle from the Horseshoe that is connected with pinching gate, connection and
remove it completely with the bridge
- Remove the screw of the lugs from both the pinching bars.
- Open out the nuts & bolts of the split body of the main valve.
- Now insert & fit the new rubber sleeve & reverse the operation to assemble the complete valve.
ADEQUATE SPARES REQUIRED
Keep adequate spares in stock - & spare sleeve should be permanently in plastic bag, safe from unnecessary atmospheric effect.
