Frequently Asked Questions

Our valve shop is located within our St. Louis facility, but we have team members at each location ready to assist you with any valve needs.

CVAC can retrofit almost any existing valve or accessory and provide a variety of repair kits or components. While CVAC doesn’t rebuild valves, we have several business partners who can rebuild/re-certify control or safety relief valves.

Each valve or primary component leaving Coyle Valve and Automation Center is given a tag and control number. If you have any questions about the product, need to purchase additional parts, or need to replace the product, our team uses the control number to pull the details of your application and speed up the selection or replacement process.

Our packages are shipped ready for installation. You don’t need to piece anything together. We do the work so it’s ready when it arrives. Coyle Supply does not perform any onsite installation.

Our tagging system makes it simple to look up your application, so you have the information you need to order replacement products.
