A client's chemical line halted due to premature valve failure. Our rapid response with certified materials restored their operations.

"We were losing over \$30,000 a day," said the plant manager of a specialty chemical facility. "The valves we bought from another supplier started failing in weeks, not years. Their seats were swelling and tearing, causing leaks and seizing the valve. We couldn't trust our process. Your team didn't just sell us a product; you gave us the right solution, and it worked flawlessly from day one." |
⊙ The Problem: Why Did a \$2M Production Line Grind to a Halt? |
|
In early 2023, a major chemical manufacturer faced a critical operational crisis. A batch of newly installed DN200 wafer type butterfly valve units were failing at an alarming rate. The specified EPDM seat butterfly valve was intended to last for over 5,000 hours of service, but catastrophic failures were occurring in under 300 hours. The EPDM seats were exhibiting severe chemical swelling and tearing when exposed to the plant's low-concentration acidic media. This caused two critical issues: the valves would no longer seal properly, risking costly product contamination, and the swollen seat would bind against the disc, making the valve butterfly valve impossible to operate. The entire production line was forced to shut down, jeopardizing contracts and incurring massive daily losses. |

⊙ The JRVAL Solution: More Than a Butterfly Valve, a Guarantee of Uptime |
|
As a dedicated butterfly valve supplier, we understood the urgency. We didn't just offer a replacement; we offered a permanent fix. Our process focused on addressing the root cause through superior materials and manufacturing. |
1. Material Integrity: The Right Choice for the Job• Correct Seat Selection: We immediately identified that EPDM was unsuitable for the client's chemical media. We recommended a PTFE seat corrosion-resistant butterfly valve, which offers superior chemical inertness and a wider temperature range, ensuring zero degradation. • Certified Body & Disc Material: To prevent any corrosion, the entire valve body and disc were specified as butterfly valve ss316. Every raw material batch was accompanied by a 3.1 material certificate, verifying its chemical composition and guaranteeing its performance against corrosion. |
2. Precision Valve Machining: Where Reliability is Forged• CNC Controlled Dimensions: Every stainless steel butterfly valve body was machined in our state-of-the-art CNC centers. This guarantees that all dimensions, from flange faces to the internal bore, comply strictly with API 609 butterfly valve standards. • Perfect Disc-to-Seat Interface: The critical step was the butterfly valve disc machining. We achieve a surface roughness (Ra) of less than 0.8 μm on the disc edge. This mirror-like finish is vital for PTFE seats, as it prevents tearing or premature wear during operation, ensuring a bubble-tight seal for thousands of cycles. |

⊙ The Result: From Costly Downtime to Seamless Operation |
|
Within 72 hours, a full batch of our PTFE lined butterfly valve units was delivered to the site. The installation was straightforward, and upon startup, the results were immediate. There were no leaks, and every butterfly valve with lever operated with consistent, low torque. The production line was back online, and six months later, a routine inspection showed the valves were performing as if they were new. As a china butterfly valve manufacturer, we know that our clients aren't just buying a butterfly valve; they are buying reliability. A component's failure is a system's failure. Our commitment is to get it right the first time by understanding the application, using certified materials, and leveraging precision valve machining to build products that last. |
|
True partnership isn't just about selling a product. It's about being the source of a solution that protects our client's process, their investment, and their peace of mind. This is the standard we deliver in every valve. |
