June 25 – Back to the Future: Lift Plug Valves Making a Come Back


Evan Hyde Facilitator: Evan Hyde – REFCOMM®

In the beginning, the preferred valve of choice for delayed cokers was the lift plug valve. For many of you who still work on older units, you know this because all your valves are still this type. Sometime around the 90’s, the shift to ball valves was swift and almost complete. In an attempt to save money, some designs used a combination of ball and gate valve for certain locations but the ball remained supreme. In recent years, lift plug manufactures have put significant effort into redesigning out the issues that gave the ball valve its clear advantage. The purpose of this webinar will be to revisit these issues and solutions so that you might once again give the humble lift plug valve a second look.
