To work with plant engineers to design a 14” three way, process cooling water control valve with a single process control that would fail in exact position upon loss of air or power and to deliver on time and under budget.
The Fail Freeze requirement was added late in the build and the initial Stainless Linkage did not pass our quality control inspection and we had to reject it and go with another vendor.
Process Supply fabricated and assembled a 14” Stainless Tee with two High Performance Pratt Butterfly Valves using an Apollo Double Acting Actuator, Custom Stainless Steel linkage assembly and VAC V400 Digital Positioner designed to fail freeze. We then operated and tested the valve at our valve automation center with our customer present for inspection.
