Our in-house injection molding machines, exclusive molds, metallic laser cutters, CNC machines, proprietary equipment and our attention to detail are the tools and qualities allowing KB Delta to provide durable, abrasion resistant and stress-free components. These are the characteristics together with our passion which gives us the ability to manufacture the best compressor valve parts in the industry and make KB Delta superior to our competitors.

Our History

KB Delta has become the premier compressor parts manufacturer and supplier of compressor valve parts for the natural gas, air, refrigeration and P.E.T. industries worldwide. KB Delta was established in 1982 by Boris Giourof, a recognized reliability specialist in the refinery and gas compressor industry.

After many years of servicing compressors, he became frustrated with poor OEM lead times and the inconsistent quality of parts. In the late 70s, Mr. Giourof developed new and innovative methods to manufacture compressor valve components. By 1981, he had established reliable fabricating processes and in 1982 launched KB Delta with the promise to manufacture high quality parts and ship them the same-day.

With more than 30 years of experience, KB Delta can proudly say we are one of the largest compressor parts manufacturers in North America. Our state-of-the-art equipment, years of engineering experience along with Boris’s dedication and commitment provides KB Delta the pleasure of assuring our compressor parts are OEM quality.
