At Blackwidow Valves, LLC, our story begins with hands-on experience. After years of running and fabricating equipment, our founder Loren Heesch saw firsthand how conventional check valves failed under pressure, causing costly downtime and frustration. Determined to build something better, he set out to engineer a heavy-duty urethane check valve that could withstand the toughest conditions. Today, Black Widow Valves delivers rugged, reliable solutions that keep lines running smoothly—because we believe equipment should work as hard as the people who depend on it.
