About Allenco

Pneumatic valve shop in Odessa, Texas.

About

Pneumatic valve work, done in Odessa.

Allenco has been working on pneumatic-actuated valves in Odessa since the early days of the Permian Basin. The shop is still here, and the work is still here.

The crew that takes a valve apart is the one that puts it back together, tests it, and ships it. We've handled enough of these valves coming back out of service to know what to look for and what to fix.

One wellsite or a fleet of compressor stations, the standards are the same.

What we do

Just pneumatic valves.

The shop is set up for pneumatic-actuated valves. Tooling, test equipment, and parts inventory are all for this work — not instrumentation, not general machining, not plumbing.

That focus is why turnarounds are quick and quotes are accurate.

How we work

How the shop runs

Four things that are just how the work gets done here.

The work itself

Every valve is inspected, machined, and tested to OEM or industry standards. If something doesn't meet spec, it doesn't ship.

Turnaround

Local shop, in-house work, and a parts inventory for the valves we see most. Most jobs don't wait on a flatbed.

Pricing

The quote is what the work costs. We stand behind what we ship. Most of our work comes from operators we've worked with before.

Safety

Our crew, your facility, and the environment. Nothing leaves the shop that isn't safe to put back in service.

  • ASME B16.34 pressure-temperature ratings
  • Hydrostatic and pneumatic testing on every job
