Winter heating season is ramping up across Texas, Oklahoma, and Kansas, and this year it's arriving on top of a tight compliance deadline. Texas gas facility operators covered under the Railroad Commission's winter rules have to file a Weather Emergency Readiness Attestation by December 1, and the industry's own numbers show gas demand climbing through the cold months even as storage sits a little above the five-year average heading into the season. None of that changes what a compression unit actually has to do: move more gas, more reliably, right when the grid and the pipelines need it most.
A worn compressor valve doesn't usually take a unit down outright. It just quietly costs you capacity, and that's the problem — it shows up as a slow efficiency loss instead of a clear failure, so it gets missed until a unit that used to hit its numbers can't anymore, right in the middle of peak demand.
The signs are usually there before a valve fully fails. A discharge temperature on one valve cap running hotter than the others on the same cylinder is one of the first tells. So is a compressor pulling more horsepower to move the same volume it used to move with less. A valve that's started to chatter or knock, or a unit that's lost discharge pressure it used to hold, is worth a look before it's worth a shutdown.
Whether a valve gets reconditioned or replaced comes down to what the inspection shows. A valve with worn sealing surfaces or a cracked plate but a sound body can often be reconditioned and put back to work. One with damage to the seat or guide, or that's been run too long past the point it should have been pulled, usually needs to be replaced outright rather than patched. Either way, the decision should follow an actual inspection, not a guess based on hours run.
When you're deciding who does that work, ask a shop how they make the repair-or-replace call, not just what they charge. Ask whether they recondition valves in-house or just swap in new ones, and whether the unit gets tested before it goes back out. A shop that can show you the worn parts and explain why they made the call they made is worth more than one that just hands you an invoice.
Disco handles inspection, reconditioning, and replacement for reciprocating compressor valves out of our shops in Borger, Texas; Liberal, Kansas; and Lubbock, Texas — keeping a unit at full efficiency instead of losing capacity to a worn valve nobody caught in time. That in-house setup means a valve doesn't sit on a truck waiting on somebody else's schedule, which matters more in November and December than any other time of year.
If a unit on your site has started pulling more horsepower than it should, or a valve cap is running hot, don't wait for a bigger failure before you call.
