VALVE SERVICE | Inspections & Repairs

At CGIS our Valve Service Solutions team provides 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.

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. 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.

Repair—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.

Calibration/Adjustments—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.

Startup/Commissioning—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.

VALVE SERVICE | Application Expertise

There is no perfect valve but there is the right valve for the application and therefore selection is key. The real challenge is finding valve experts who can analyze the process and recommend the appropriate valve for the presented conditions. CGIS is committed to understanding the application, well before a dollar is spent, to ensure our customers always get the right valve. Our team assures that all necessary information is collected before making a recommendation so that you always get the best valve for your application.

VALVE SERVICE | Control & Isolation Demonstrator (CID)

To demonstrate our commitment to the application, we have built a Control & Isolation Demonstrator (CID) to see real-time, unbiased valve results. CID is a custom-designed comprehensive flow demonstration loop used to test our products and our competitor products. The parallel piping sections allow comparisons of up to three valves at the same time. We invite clients to visit our Vancouver facility in person to watch real valve performance, to request alternative installation and trials, and to provide a basis for valve selection that removes doubt and guesswork.
