SERVICE | Focused on the Customer

CGIS’ growth depends on building honest, long-lasting customer relationships. To this day, our first customers are still in business with us, 40 years later. Our Service & Repair departments focus on Inspection & Repairs, Automation, and Consulting.

Valve Servicing

24-Hour Valve Service Line

At CGIS our Valve Service Solutions teams provide a wide range of services including repair, troubleshooting, on-site installation & commissioning, training and maintenance for all your valve needs.

Our factory authorized technicians are available to assist with your troubleshooting issues, from the initial phone call to the broader, extended stay visits, when on-site work is needed to ensure the job is done correctly.

Inspections & Repairs

In-House Services

Our Service Centres are equipped with the personnel, equipment, and machinery needed to conduct repairs for all the valve and automation products that CGIS represents.

The CGIS Valve Service Solutions team is trained to inspect, evaluate, assemble to factory standards, providing our customers with comprehensive service reports.

Our facilities are equipped to perform a range of NDE, including hydrostatic, electric and pneumatic testing. We have the capability to test a wide array of valve products ranging from the small (1/2”) to the very large (42”), up to ASME class 4500, and everything in between.

As a manufacturer representative and authorized repair centre, we only use Original Equipment Manufacturer (OEM) parts and maintain a substantial inventory to ensure a quick and timely turnaround.

To complement our inventory, our manufacturers maintain a wide range of critical spares along with quick ship programs, further enhancing our ability to meet ever-tightening deadlines for the repair and refurbishment of valves.

Design and Drafting:
In-house 3D Solid Works and 2D AutoCAD capabilities.

Spare Parts Inventory Program:
Do you have valves that have known regular repairs or spare parts?
Ask us how we can design a program for you.

Field Services

Evaluation and Inspection:
Our trained personnel can complete valve evaluations and walk downs in-situ. Eliminate future issues and reduce downtime through early detection and analysis.

Preventative Maintenance:
Procedures such as proper greasing and packing adjustments ensure optimal operation for the long term, making sure you won’t have any surprises.

Our factory trained and fully equipped personnel provide quick, onsite repairs for common issues. If the job is too complex to be completed onsite, the valve will be shipped to our In-House service team for proper repair.

Valves require properly trained personnel to ensure the calibration and adjustments are completed correctly. Our technical staff is specifically trained to do so with elite level precision to warrant a longer valve life.

Valves are complex parts of any process system, especially if they are actuated or part of a larger BUS or PLC system. Startup commissioning is one way to ensure your valves are set properly once installed and are ready to perform.

Control Valve Support:
In conjunction with Flowserve, we are able to provide high quality, experienced personnel that can troubleshoot, install, and repair these complex valve assemblies to ensure optimal performance.
