The plant had two main steam isolation parallel slide gate valves (PSG’s) installed in this application. They were experiencing severe leakage when valves were required to isolate. The cost of $40,000 per repair, was a particular concern far the plant. Management decided to look at their alternatives far an upcoming outage.
ValvTechnologies’ decades of engineering experience led to the design of its superior, severe service zero-leakage isolation valves that exceed industry standards. In this case, it also led to ValvTechnologies’ largest ever h-oil project win and the displacement of a former firmly ingrained competitor.
A US chemical plant using wedge gate valves leaked so severely that steam passed through the valves and into the turbine making it impossible to perform turbine maintenance repair. The plant would have to be completely shut down so that the turbines could be accessed. With each occurrence, the cost associated with shutting down the […]
During a routine maintenance inspection at a petrochemical plant in the Texas Gulf Coast, technicians found a defective double ball valve that was installed in the reactor block valve application. Learn how ValvTechnologies utilized its unique zero-leakage valves with RiTech® coating to engineer a cost effective and time saving solution.
The client, a bitumen upgrader based in Canada’s Oils Sands, was experiencing heavy run-time and reliability issues due to coking up in their Inlet feed Coker valves, leading to significant damage and performance issues, and therefore rising costs due to unplanned downtime. ValvTechnologies high performance purge design solution performed beyond expectations and eliminated the need […]
ValvTechnologies’ zero leakage hi-performance isolation valves saved millions of dollars to Ecopetrol Delayed Coker Unit, allowing them to replace overhead bottoms valves without shutting down the whole unit.
