In this world of intense global competition, it’s a wonderful thing when we receive a testimonial from one of our customers. Thank you to all of our customers who have taken the time to express their appreciation for our products and services.

Before switching to the ANCORP XL ball valve design, air leaks into our vacuum exhaust lines through the stem seal on the standard (OEM) ball valves were a major source of unplanned downtime.  In addition to the lost productivity and direct repair expenses, we also suffered collateral expenses due to reactions between the atmosphere and the process gasses in the exhaust line.

With the introduction of the ANCORP XL ball valve has completely eliminated this costly failure mode, resulting in significant cost savings and increased equipment uptime.  The XL ball valve design has exceeded our expectations; we are extremely pleased with its performance.

Sandy has saved my life, as I was having nightmares about this job! I have contacted over a dozen companies and was getting ready to submit an order with a company that had an eight-week lead time to manufacture these specific bellows. I will certainly be using you for my UHV parts in the future! I make scientific apparatus for various universities in the state of Maryland, as well as space flight Center. I have been welding for over 50 years.

I really appreciate working together with Manny and his team. Keep up the good work!


Manny is unbelievably patient and very knowledgeable. He has made my first experience with Ancorp eye-opening. I have used your competitors exclusively over the last 20 years, but I think a switch is in the making.

Every time I place an order with ANCORP, I never have any issues. CS is always excellent!!!
