Built on Precision. Certified for Service.
Cornerstone Valve was founded by women with deep roots in industrial procurement — built to serve the agencies and contractors who need a reliable, certified valve supplier.
Our Story
Cornerstone Valve was founded with a clear mission: to bring precision-engineered industrial valves to government and commercial procurement teams through a certified, women-owned supply channel.
Our founders recognized a gap in the market — procurement officers needed a WOSB-certified valve supplier that could deliver on quality, documentation, and lead times without compromise. Cornerstone Valve was built to fill that gap.
Today, we supply gate, ball, check, butterfly, globe, and needle valves to federal agencies, defense contractors, and industrial facilities across the country. Every order ships with full compliance documentation.
Mission & Values
To be the most trusted WOSB-certified valve supplier in federal and industrial procurement — delivering precision products, complete documentation, and responsive service on every order.
