Manual Pinch Valves Series 9000
Red Valve Manually Actuated Pinch Valves are reliable, maintenance-free, cost-effective valves engineered for tough slurries, abrasives, and corrosive chemical applications. The 100% full port design eliminates any dead spots or crevices, seats or bearings where slurry can hang up and impair operation or even cause complete valve failure. Manual Pinch Valves feature bi-directional droptight shutoff in a design that meets the same face-to-face dimensions as gate, plug, and ball valves up to 12". Manual Pinch Valves employ Red Valve's state-of-the-art elastomer technology to provide smooth venturi flow, centerline closure, and excellent throttling characteristics. A number of options are available, such as the Series 75B design for buried-service conditions. AWWA nuts, chainwheels, stem extensions, and bevel gear actuators are also available

The Series 9000 high-pressure manual pinch valve is designed with ANSI Class 300 flange drilling. The heavy-duty elastomer sleeves are reinforced with high strength nylon, polyester fabrics, or Kevlar® material. Several heavy-duty sleeve designs are available. The elastomer sleeve will close even on solids, and the flexing action of the sleeve eliminates the possibility of scaling. Two heavy-duty pinch bars close the sleeve. All valve working parts are isolated from the process by the sleeve. Combining these features with a sealed body design and no packing to maintain, results in a simple, rugged, no-hang-up, maintenance-free valve.
Several bevel gear actuators are available for On/Off manual operation.
In order to accommodate the higher working pressure design, the valve is normally sized one size larger to allow for the thick double wall high pressure sleeve. As shown on the chart below, a 6” port size valve requires a 8” flange body size. Series 9000 designs are also available in ANSI Class 150 designs, and are available with pneumatic, electric, or hydraulic actuators
