High Quality Products

Red Valve products are used extensively in handling cement, sand and silica due to the highly abrasive nature of these materials. Red Valve pinch valves feature a 100% full-port opening for maximum flow, wet or dry. The high-quality elastomer pinch sleeve can last up to 3 times longer than an all-metal valve, and it is the only replacement part. There are no crevices or dead spaces in a pinch valve where material can collect, and the flexibility of the sleeve allows it to close drop-tight.
