About Advanced Process Services

After decades in the process control world, working for manufacturers like Mason Neilan, Valtek, and a division of Tyco Valve; Tom Burdi saw a recurring problem...

Customers were stuck whenever a critical valve failed and parts were unavailable, back-ordered, or discontinued. Lead times of six months or more were not uncommon, and planning departments often had CNC machines booked far into the future, leaving plants waiting and losing money.

Tom founded Advanced Process Services with a simple goal:

Build a company that can repair, rebuild, or reproduce critical components quickly. Even when OEMs say it can’t be done, and do it at a cost that makes sense for the customer.

By focusing on in-house machining and welding (manual “one-off” capability, not just mass production)

Smart material choices and upgrades

Vendor partnerships for heat treatment, boronation, and grinding

Honest communication and realistic timelines

APS has become the shop that other repair companies and manufacturers send their “impossible” jobs to.

Frequently Asked Questions

Common Questions Answered for your convenience.

What does Advanced Process Services do?

We specialize in repairing, rebuilding, and upgrading industrial valves, actuators, and process control equipment. Instead of waiting weeks or months for new OEM parts, we restore and improve your existing equipment using our in-house machine shop, weld shop, PMI testing, and advanced surface treatments.

Which industries do you serve?

Our clients include refineries, petrochemical and chemical plants, power plants (including geothermal), pipelines and fuel distribution firms, industrial gas companies, food processing facilities, pharmaceutical operations, and aerospace/test facilities. We’ve worked with companies like Valero, Phillips 66, Marathon, Kinder Morgan, Parker Hannifin, Honeywell, Matheson Gas, and others across the U.S.

How do you improve valve performance beyond basic repair?

We look beyond simply restoring a valve to its original condition. APS evaluates the actual service conditions — pressure, temperature, chemistry, and abrasion — and upgrades materials, surfaces, and internal designs when needed. This includes using better alloys, hardfacing, sleeves, and surface treatments so the valve lasts longer, seals better, and performs more reliably in its real operating environment.

Can you help when parts are obsolete or discontinued?

Yes. This is one of the main reasons customers come to us. We can clone existing components in our machine shop, repair worn parts, upgrade materials, and bring legacy valves and devices back into service even when manufacturers no longer support them.

Where are you located and what regions do you serve?

We’re based in Commerce, California, and regularly serve clients across Southern California, as well as other parts of the United States. Valves are shipped to us from places like Nevada, Arizona, New Mexico, Hawaii, and beyond.

What kinds of valves and equipment can you work on?

We work on a wide range of equipment, including globe valves, ball valves, butterfly valves, gate valves (as block valves), check valves, relief valves, actuators (pneumatic, hydraulic, and electric), vapor recovery valves, flame arrestors, and more. We also repair gearboxes and can fabricate new gears when originals are worn or obsolete.

How fast can you turn around a repair?

Typical repairs take from a few days to a couple of weeks, depending on complexity and scope. For critical situations, we’re set up to respond quickly — we’ve turned valves around in as little as four hours when a process was down and time was critical.

How does your pricing compare to buying new valves?

In many cases, we can rebuild a valve and provide a one-year warranty for about half the cost of a new valve. It only makes sense to go beyond that — up to maybe 60–70% of new — when a new valve is unavailable for an extended period (for example, a year-long lead time) or when your schedule can’t wait for OEM delivery.

Do you only work in your shop, or can you come on-site?

We do both. Our fully equipped shop handles major rebuilds and complex machining, and we also have a mobile trailer for on-site work, turnaround support, and smaller instrumentation jobs. For very large valves or extensive work, we typically bring them back to the shop for full repair and testing.

How do you ensure you’re using the correct materials?

We use a Positive Material Identification (PMI) device to verify the exact alloy of trims and components. Manufacturers sometimes use cost-driven material choices that don’t hold up in certain services (like H₂S). We analyze the actual material and process conditions, then recommend and install materials that will perform better over the long term.
