We are a family owned company based in Oklahoma City. We produce 100% American made High Quality Safety Relief Valves that are used in a variety of applications. We now have a Canadian Division and plant that builds and assembles the valves right here in Alberta. Our patented "Auto Seat Technology" ensures proper alignment over and over and allows for owner/operator peace of mind. We're thrilled to be a part of ISA Alberta Directory and look forward to meeting our present and future customer's needs!
