We are revolutionizing manufacturing with our unique Modular Rotary Valve designs and premium custom machines. There are rotary valves, feeders, or screw conveyors that are priced less than Precision, but none that make you more efficient, more productive, or more profitable. For moving virtually any dry, granular or powdery material smoothly in measured amounts, nothing performs better. The built-in quality of the materials and finishes we use easily handles abrasive substances like fly ash, coal, coke, volcanic cinders, diatomaceous earth and pebble lime. Our innovative engineering department and skilled craftspeople work with customers to create unique solutions that give them a competitive edge by increasing throughput, improving efficiency, and maximizing uptime. Are you pushing productivity? We can help.
