Fluid catalytic cracking (FCC)
Delta Controls is an international service and repair center for refurbishment, overhaul and modification of FCC slide valves, plug valves, ball valves, gate valves and butterfly valves. Including all controls together with associated pneumatic/hydraulic/electric actuators.
FCC slide valves
These critical Fluid Catalytic Cracking valves function under high temperatures, normally 760 °C. The FCC units control the proces which is originally designed by contractors and manufacturers according:
- Stone and Webster
- Exxon Flexicoker
Delta Controls started the FCC activities in the early 1970’s. As an independent company, we developed a high expertise and have experience for over 35 years now.
The formula of Delta Controls success is that Delta Controls is co-operating in an excellent harmony with all customers. Being independent and supported by engineering companies we implement all combined experiences of different applications.
The Delta Controls service concept
Our service concerns ‘Total Product Life Cycle Care’ for your Valves and Actuators. In the ‘Product Life Cycle’ of Valves and Actuators there are four specific stages: the specification phase, the installation and start-up phase, the operational phase and the post-operational phase.
Being independent, we know all advantages and disadvantages of all brands and therefore we will inform our customers for implementing modifications, reducing customers total maintenance costs.
No strings attached
It’s our obligation to inform each customer without any restriction about all construction details, errors, mistakes made by the original manufacturer and to improve the quality of your valves as you are the owner.
All our work is and will be carried out according the international QA/QC standard ISO 9001:2000. Delta Controls is also officially registered to Safety Checklist Contractors (SCC) VCA ** 2004/04 since 1996.
Knowledge and experience
Our service engineers have a high education, responsibility and high morals. They also perform field service during a turnaround therefore they know the practical applications and requirements of each customer.
A one stop shop
All our manufacturing is carried out in our workshop, welding, stelliting, refractory applications, stress relieving, curing, grinding, machining, etc, against the highest specifications and requirements of each individual refinery.
Our in house techniques are special welding, machining, instrumentation and hydraulics. There is no split up, as we see the valve with actuator and controls as one package guaranteed by us for a non interrupted performance and lifetime.
Impressions of Field service activities
Delta Controls started as a service company for the petrochemical industry. Since the start Delta Controls has invested in up-today service equipment. Starting form the smallest special tool untill full-equiped service trucks, together with full-equipped service busses and 20 feet workshop containers.
