Our Products
Cylinder Airlocks
Using our patented Zero-Leak™ technology, the Sigco Cylinder Airlock is designed to feed dry solids material between two different pressure zones with no static leakage. Maintenance is a breeze with our drop-in replaceable parts.
Cylinder Feeders
Sigco Cylinder Feeders are designed to efficiently send material between different pressure zones using a special density-reading method to ensure accurate quantities. There is no static or dynamic leakage, saving your resources.
Cylinder Valves
For use on pressure and vacuum services, our Cylinder Valve keeps your flow controlled - open or closed. Plus, with no cavities for material retention, our Cylinder Valve won't crush your material between closure members.
About Sigco
Small Company, Big Ideas
It all began as a simple innovation by Jim Sigmon back in 1987. Since then, Sigco has transformed industry standards, redefining rotary airlocks and valves, and carving out an unbeatable niche.
Revolutionary Design
Our key to success is a patented design with a durable build that eliminates abrasion and air leakage from your systems. Our unique product design keeps your systems running better - and longer - saving you time and money.
The Zero-Leak™ Difference
Our signature (and exclusive) feature. Sigco Zero-Leak™ technology controls air flow, stops abrasion and conserves resources. Because leakage control is so critical, this patented technology sets us apart from the crowd.
Always Striving to Improve
Since our inception, we have relentlessly pursued perfection - improving designs and redefining industry standards for products like airlocks, rotary valves and volumetric feeders. Because we believe in innovation, we know we can never stop improving.
Never complacent, in 2010 we released an updated line that introduced new products and featured enhanced innovations for existing products.
