Molecular Sieve Switching Valves Superior Design
Application: Sour gas molecular sieve
Product: V Series molesieve switching valve

Facing hundreds of millions of dollars in production losses annually, a major global oil company placed a multimillion dollar order with ValvTechnologies for molecular sieve switching valves to replace their existing rising stem ball valves.

High Pressure Protection Systems (HIPPS)
Product: HIPPS

The customer placed a large order for HIPPS trunnion valves, which were 8” class 2500. The scope was a total of 20 valves which were needed for the expansion of their gas field. Their excellent experience with ValvTechnologies’ on a previous order influenced them to choose our services again. 

Molecular Sieve Dehydration Unit Success Story
Application: Molesieve dehydration units
Product: V1-4

The customer switched to ValvTechnologies’ V1-4, solid Inconel 825 and the valves lasted for two years vs. the competitor’s 1-90 days and saved them millions of dollars of lost production. The customer has now standardized on ValvTechnologies’ valves in all their molecular sieve units. A second order was placed for 74 V Series valves, sizes 12” and 16” in solid Inconel.

DOWNSTREAM & CHEMICAL PROCESSING

Delayed Coker Train Isolation
Plant type: Refinery
Product: V1 metal seated Coker

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. 

ValvTechnologies' Purge Design Saves More Than Half a Million Dollars
Location: Canada's Oil Sands
Plant: Upgrader
Application: Inlet feed coker valves

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 for costly servicing and replacement valves and over time increased production rates and overall plant operations. Learn more about the high-performance Coker valve purge design.

V1-2 Engineered Solutions
Application: Reactor block valve
Product: V1-2 with HVOF RiTech® coating

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.

TrunTech® Dosing Cup Valve
Product: TrunTech® trunnion dosing cup

A Texas polyethylene plant had valves grouped in a pair of fours with a drive system that could operate one or multiple valves as required. Instead of a traditional hole through the valve, these unique valves had a dosing cup that metered catalyst into the reactor, rotating 360° based on the drive system. Read more to learn how ValvTechnologies custom-engineered a first of its kind solution to meet the plant's unique needs.

Service Department - Customer Support
Product: Customer support, inspection & product servicing

One of our oldest customers is a large refinery in the Texas gulf area. They have several hundred ValvTechnologies’ valves installed: many of them are specially engineered designs and unique materials of construction for tough service applications in their refining units. A large number of these valves have been in service for more than 15 years. 

Turbine Isolation & IsoTech® Parallel Slide Gate Valves
Product: IsoTech®

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 plant was several million dollars per shut down.  

Coking - Heater Isolation Success Story
Application: Furnace heater isolation 
Product: V1-2

ValvTechnologies committed to the customer’s short lead time requirement based on their on-site delivery needs by offering expedite options with existing coker inventory/stock, changing out to forgings where able and working with valued suppliers to expedite materials with negligible impact on overall project cost.
