Oil Industry Valve Case Study | Fleyenda Valve Supports Major Kazakhstan Refinery
“Delivering Reliable Valve Solutions for Over 40 Years of Oil Refining Excellence”
1. Project Background
One of the largest oil refineries in northeastern Kazakhstan (hereinafter referred to as “K Refinery”) is among the top three refineries in the country, established in the 1970s. The refinery operates a full set of processing units, including:
-
Crude distillation
-
Deep processing units
-
Residue treatment systems
For more than four decades, K Refinery primarily relied on European valve brands. However, as equipment aged and maintenance demands increased, the refinery began seeking more flexible, cost-effective, and responsive valve suppliers in the oil industry.
2. Cooperation Opportunity
In 2021, K Refinery initiated its first collaboration with Fleyenda Valve through a local EPC contractor.
Over the following four years:
-
Fleyenda supplied both manual valves and automated valves
-
Gained deep understanding of refinery-wide requirements
-
Supported multiple units with continuous valve delivery
The refinery’s valve demand covered a wide range:
-
Size range: 1/2” to 40”
-
Pressure rating: PN10 to PN420
-
Valve types: manual valves, electric actuated valves, pneumatic valves, and control valves
By 2025, impressed by consistent performance, K Refinery invited Fleyenda Valve for on-site technical exchange, opening collaboration across six major processing units.
3. Challenges and Requirements
Wide Specification Range
The refinery required both:
-
High-pressure forged valves
-
Large-diameter low-pressure valves
This demanded a supplier with a complete product portfolio.
Strict Technical Compatibility
All valves had to:
-
Match existing European standards
-
Integrate seamlessly with PLC and DCS systems
-
Fit current pipeline layouts and safety interlock systems
Urgent Maintenance and Turnaround
With limited shutdown windows, the refinery needed:
-
Fast technical clarification
-
Accurate valve selection
-
Short delivery time
-
24/7 after-sales support
