How a mid-sized engineering firm optimized their valve procurement strategy for a coastal water treatment facility by partnering with us for their manual isolation valve needs.
Client: A prominent mid-sized water engineering company in Jordan.
Project: Expansion of a pre-treatment facility for a desalination plant near Aqaba.
Contact: Tariq Al-Fayez, Senior Procurement Engineer.
Mr. Al-Fayez was tasked with procuring over 200 manual wafer butterfly valves (DN80 to DN300) for the facility's new low-pressure pipe network. The primary challenge was balancing a tight project budget against stringent long-term reliability requirements. The media consisted of screened seawater and chlorinated process water, a moderately corrosive environment that had caused premature failure in lower-grade valves on past projects.
The market presented Mr. Al-Fayez with two unsatisfying options: premium European brands that would inflate the valve budget by over 40%, threatening project viability, and low-cost regional suppliers whose material certificates were often questionable. His previous experience taught him that valves meeting the "SS316" specification on paper could still fail within 12-18 months due to inconsistent casting quality and lower-end alloy composition.
Instead of promising the impossible, our approach focused on transparently demonstrating how we manage quality at the source. This resonated with Mr. Al-Fayez's engineering background. The solution was built on three core pillars:
We demonstrated our key differentiator: our 81,426m² facility includes an in-house foundry, managed by our founder with over 20 years of casting expertise. This allowed us to provide not just standard Material Test Reports (MTRs), but also detailed evidence of our process. For their AeroForm CF8M valves, we supplied melt analysis data showing a consistent Nickel content between 10.5% and 11.5% and a PREN value consistently above 25, providing a quantifiable margin of safety against pitting corrosion from chlorides. This verifiable data gave them more confidence than a simple MTR from a supplier who outsources casting.
The AeroForm's robust design was a direct fit. The lockable hand lever was critical for their LOTO (Lock-Out/Tag-Out) safety procedures during pump and filter maintenance. Furthermore, our proprietary seat design achieves a bubble-tight shutoff (meeting ISO 5208 Rate A) through structural integrity, not by over-compressing the elastomer. This detail was crucial for Mr. Al-Fayez, as it directly addressed the common failure mode of premature seat wear and leakage. All dimensional checks were documented in our standard QC reports, generated from calibrated instruments on our 11 CNC machining centers.
We offered the AeroForm series at a price point that resulted in an 18% saving on their total valve procurement budget compared to the quotes from established Western brands. Crucially, this was backed by a 24-month warranty covering all components, including free replacement of wear parts (seats, O-rings). We were also transparent that while our in-house QC is rigorous, site-specific third-party inspection (e.g., by SGS or Bureau Veritas) could be arranged at their cost, giving them full control and verification options.
Our commitment to quality is verified by internationally recognized standards. We provide the documentation to prove it.
Ready to configure for your automation project?
Our reliability comes from controlling quality at the source. As a factory that integrates casting and machining, we use an enriched high-nickel content (up to 9% in CF8) in our steel. This, combined with our 20 years of casting expertise, results in a stainless steel wafer butterfly valve with superior corrosion resistance and a porosity-free body for maximum durability.
Absolutely. Every AeroForm series stainless steel wafer butterfly valve is built with a standardized ISO 5211 mounting pad. This future-proof design allows you to easily remove the hand lever and mount a pneumatic or electric actuator later without needing to replace the entire valve, protecting your initial investment.
We provide full traceability for every valve. Your order will include complete Material Test Reports (MTRs) and our factory QC inspection data. All our products are backed by a comprehensive 2-year warranty, giving you peace of mind and demonstrating our confidence in the long-term performance of our valves.
Buying factory-direct means you get better value, direct technical support, and greater transparency. You bypass middlemen, reducing costs.
