Manual Pinch Valves Series 75B
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 75B manually operated Pinch Valve is a reliable, maintenance-free, cost effective valve designed for tough slurries and abrasive and corrosive chemical applications below ground. This intrinsically safe Pinch Valve, which was developed specifically for underground service, is sealed with an epoxy coating and features an above ground position indicator for instant identification if the valve is open, closed, or is in the throttled position. There are no seats to grind, no stuffing boxes to repack, and no packing gland to adjust, ever, with the Series 75B. The pinching action is on centerline so the valve closes on a smooth venturi and is self-cleaning.
The heart of this unique valve is the durable, flexible rubber sleeve which is reinforced with high strength fabric. The sleeve, which is the only part of the valve exposed to the process, eliminates maintenance and the need for expensive, exotic body materials. Additionally, valve operation will not freeze and operating torques remain constant.
Series 75B Pinch Valves have the same face to face as gate, plug, or ball valves, ANSI 16.10 up to 6” size; sizes 8”, 10”, and 12” Series 75B’s are available to ANSI 16.10 face to face with Reduced Port Sleeve
