Carbon Steel Flange Butterfly Valve - Bare Stem

Supply Chain Volatility & Quality Fade

A major European distributor, supplying valves for demanding petrochemical applications, was facing increasing supply chain volatility. Their previous suppliers provided valves that initially passed inspection but suffered from premature seal failure and corrosion, especially for non-standard material orders like Duplex and Super Duplex steel. This "quality fade" was damaging their reputation and putting critical client projects at risk.

The High Cost of "Cheap"

They were trapped between two undesirable options: paying exorbitant prices for major European brands with long lead times, or gambling on low-cost suppliers whose lack of material control and inconsistent machining led to unacceptable total cost of ownership (TCO) due to failures, downtime, and replacement labor.

The Need for Manufacturing Transparency

The client urgently needed a partner who could not just supply a product, but also provide verifiable proof of quality. They required a manufacturer who could handle complex material specifications and provide comprehensive documentation to satisfy their end-users' stringent quality assurance requirements.

Solution: A Partnership Built on Proof

We proposed a trial order for their most challenging requirement: a batch of Super Duplex F55 butterfly valves. Our approach was not to just deliver a valve, but to deliver a comprehensive quality package. We showcased our core strengths:

• Advanced Metallurgy: We provided full material traceability, starting with PMI verification of the raw Super Duplex steel to ensure a PREN value exceeding 40. Heat treatment curve records were supplied to prove the correct austenitic-ferritic phase balance was achieved.
• Protective Coating Systems: Each valve received a 250μm epoxy coating, with a detailed WPS (Welding Procedure Specification) and ITR (Inspection and Test Report) to validate the process.
• Total Quality Assurance: Every valve was delivered with a complete documentation dossier, including MTRs and hydrostatic/pneumatic test certificates, giving the client undeniable proof of quality to pass on to their customers.

Result: From Supplier to Strategic Partner

The trial valves exceeded the client's internal testing protocols for both bi-directional sealing and material composition. By providing manufacturing transparency, we eliminated their supply chain risk. They now had a reliable source for high-specification valves at a price-to-performance ratio that major brands couldn't match. This allowed them to bid on and win more lucrative projects. We have since become their go-to partner for all non-standard material requirements that other factories are unable or unwilling to produce.
