Pinch valves and rubber lined slurry valves are purpose built for media that destroys conventional valves: abrasive mineral slurry, tailings, corrosive chemicals, and solids laden flows. The flexible rubber sleeve is the only part in contact with the media, giving a full bore, unobstructed flow path with no crevices, pockets, or metal wear surfaces.
AQ Process Systems sources and exports pinch and slurry valves from certified Indian manufacturers experienced in mining and mineral processing. Our range covers open and enclosed body pinch valves for isolation and control, in sizes from 1 inch to 24 inch, with a wide choice of sleeve elastomers, natural rubber, NBR, EPDM, neoprene, and polyurethane, selected for the specific abrasion and chemical conditions.
Because the replaceable sleeve is the only wear part, pinch valves offer very low maintenance cost in severe slurry duty, and the same design provides excellent throttling control. This complements our knife gate range and is central to the mining, copper, gold, and mineral sectors we serve across Africa and the Middle East, at 25 to 40 percent below Western pricing.

| Product | Specification | Description |
|---|---|---|
| Pinch Valves | ||
| Open Body Pinch Valve | 1" to 12" | Exposed Sleeve | Manual/Actuated | Economical open frame design with exposed elastomer sleeve pinched by a mechanism. For isolation and control of abrasive slurry, powders, and granular media. |
| Enclosed Body Pinch Valve | 1" to 24" | Full Housing | Air/Hydraulic | Fully enclosed body with the sleeve pinched by internal air or hydraulic pressure. For higher pressure slurry, corrosive, and hazardous media requiring full containment. |
| Control Pinch Valve | 1" to 16" | Modulating | Positioner | Pinch valve with positioner for accurate modulating control of slurry and abrasive flows, combining throttling and isolation with minimal wear. |
| Rubber Lined Slurry Valves | ||
| Rubber Lined Slurry Gate | 2" to 48" | Fully Lined | Bidirectional | Knife gate style body fully lined with abrasion resistant rubber and replaceable sleeves for heavy tailings and concentrate slurry isolation. |
| Rubber Lined Butterfly (Slurry) | 2" to 48" | Full Lug | Abrasion Rubber | Fully rubber lined butterfly for slurry and process water isolation, resisting abrasion from mineral concentrate and tailings. |
| Sleeve Options | ||
| Elastomer Sleeves | NR / NBR / EPDM / Neoprene / PU | Replaceable sleeves selected for the abrasion and chemistry: natural rubber and polyurethane for abrasion, NBR for oils, EPDM for chemicals, neoprene for general service. |
