Independent industrial valve repair, testing, and refurbishment for refineries, power plants, chemical facilities, manufacturing plants, and pipelines — performed with precision, verified through testing, and backed by complete documentation.
Trusted by the industries where reliability cannot be compromised
GT Industrial Valve Service is an independent industrial valve service company specializing in the repair, maintenance, testing, and refurbishment of critical flow control equipment. We provide professional valve services for customers operating in industries where equipment reliability is essential.
Our experienced technicians understand that every valve plays a critical role in maintaining safe and efficient operations. From routine maintenance to complete valve rebuilding, every project is performed with precision, attention to detail, and a commitment to quality.
Our objective is simple: help our customers reduce downtime, extend equipment life, and improve operational reliability.
From body and bonnet to stem, gland, and handwheel — every component is inspected, machined, and reassembled to exact tolerance. Spin the model to see the kind of equipment we restore to reliable service every day.
Drag to rotate
Our mission is to restore reliability, extend the service life of critical assets, and help our customers operate with confidence. Every valve that enters our facility is treated as a critical component of our customer's operation.
Comprehensive service for critical flow control equipment — from routine maintenance to complete valve rebuilding.
Inspection, restoration, and re-sealing of butterfly valves to return them to dependable service.
Complete disassembly, machining, and reassembly to restore valves to reliable operating condition.
Certified pressure testing to verify integrity and confirm every valve is ready for service.
Air/gas seat and shell testing to validate sealing performance under operating conditions.
Inspection, repair, and set-pressure verification of safety and relief valves.
Service and calibration of control valves to maintain precise, reliable process control.
Controlled, precision machining of sealing surfaces and components to exact tolerances.
On-site valve service to support your operation where and when you need it.
Fast-response repairs to minimize downtime when an unexpected valve failure occurs.
Complete inspection reports, test certificates, and certificates of conformance for traceability.
If it controls flow, we can restore it. We service every major valve type — regardless of size or manufacturer.
Valves fail in predictable ways — and every one of them costs you uptime. These are the issues we diagnose, repair, and verify every day.
Internal and external leakage from worn seats, seals, and gaskets — re-lapped, re-sealed, and leak-tested back to a positive shut-off.
Pitted, scratched, or eroded sealing faces precision-machined and lapped back to the original tolerance for a reliable seal.
Corrosion, erosion, and process damage to bodies and internals assessed, repaired, or replaced to restore structural integrity.
Valves that won't stroke, bind, or hold position freed up, rebuilt, and cycle-tested so they open and close on demand.
Stem leakage, worn bushings, and failed packing rebuilt with new components for smooth, leak-free operation.
Pneumatic, hydraulic, and electric actuators serviced, calibrated, and stroke-verified for fast, repeatable response.
Wherever fluid or gas has to be controlled safely, our valves are on the line. We support the operations that can't afford to fail.
Isolation, control, and safety relief valves on high-temperature, high-pressure process lines where a leak is never an option.
Large-bore block, isolation, and check valves that keep product moving and shut it down instantly when it has to stop.
Steam, feedwater, and cooling valves serviced and tested to keep generating units online and operating safely.
Corrosion-resistant and specialty valves restored to handle aggressive media with a dependable, documented seal.
Gate, butterfly, and check valves rebuilt to keep treatment and distribution systems flowing reliably.
Process and utility valves across plants and facilities maintained to reduce downtime and extend equipment life.
A single valve failure can interrupt production, create safety risks, increase maintenance costs, and impact environmental compliance. Unexpected valve failures can result in:
True reliability begins long before equipment is returned to service. Only then can equipment return to operation with confidence.
More than a repair facility — a reliability partner. Every decision we make is focused on one objective: restoring reliability.
Every valve is evaluated individually. We identify the root cause of failure rather than simply replacing damaged components.
Every repair uses precision measuring instruments, controlled machining processes, and documented inspection procedures.
Customers receive detailed inspection reports, repair recommendations, testing documentation, and complete service records.
We understand downtime costs money. Our goal is to return equipment to service quickly — without compromising quality.
A properly repaired valve isn't simply a completed job. It is an investment in the reliability of an entire facility.
Every repair carries our name — tested, verified, and documented before it leaves our facility. Because your reliability is our reputation.
Every valve — regardless of size, manufacturer, or application — is serviced according to one internal quality philosophy, built on six principles.
"Quality is never assumed. It is verified."
From the moment equipment arrives until it is returned to service, every process is focused on restoring reliability.

Everything we do is guided by a simple set of principles. These values define who we are.
Nothing is more important than protecting people and facilities.
Every repair must meet our standards before it meets the customer's expectations.
We do the right thing even when nobody is watching.
Attention to detail separates acceptable work from exceptional work.
Every repair carries our name. We stand behind our work.
Every project teaches us something. Every day is an opportunity to become better.
Professional repair requires more than technical expertise — it requires complete documentation. Every valve serviced by GT is accompanied by records that provide complete traceability throughout the repair process.
Complete documentation provides confidence that every repair has been performed according to established procedures and verified through inspection and testing.
Every valve protects something. Every repair prevents something. Every inspection verifies something. Every customer depends on something.
