AboutOnyx Valve

A major pinch valve manufacturer in South Jersey was bought out by a multi-national corporation which subsequently closed the operation in 1994.  Six former employees of this company started Onyx Valve Co. on May 1, 1995. Since then our customers have made us the fastest growing pinch valve company in the world. We have since expanded to a 50 person workforce allowing us to help lead flow control industry with using both innovative and simplistic techniques to fit each of our customer’s needs. All Onyx Valve products are designed and manufactured in our modern factory located in Cinnaminson, NJ. All our rubber pinch valve and check valve sleeves are made in-house to our exact specifications by the most experienced molders in the industry.
