We offer a full line of one-way Urethane Check Valves from 4 inch down to a 1.5 inch. We Build a valve that fits tight on the pipe and has a long-lasting hinge for multiple applications of vacuum conveying from resin pellets, dog food, sand, flour, sugar, cement powder most anything transferred through a vacuum system. We can also custom fit or build a one-of-a-kind valve that suits your needs.

Blackwidow Valves form a tight seal to achieve the tightest possible seal to prevent backflow, even at low volume rates. Our flexible one-piece rubber design allows the valve to compress and open under heavy or minimal vacuum loads

Hello, my name is Loren Heesch, Designer and fabricator at Blackwidow Valves, LLC. I have worked in the plastics industry for over 37 years and I became very disappointed with the quality of the valves that are on the market. So we put our heads together and built a stronger valve out of tough material that holds up over  time and high pressure. By designing a better product, we now can offer a Heavy-duty valve at a lower cost to you.
