For engineers and procurement specialists, the corrosion performance of Ductile Iron and Stainless Steel Non-Rising Stem Groove Gate Valve designs often becomes the deciding factor. At Tianhong, we have tested both materials across thousands of installations—from municipal water treatment to offshor......

When selecting a Stainless Steel Butterfly Valve for critical flow control systems, the seat material often determines the valve’s longevity, safety, and operational efficiency. Among the most debated choices are EPDM (ethylene propylene diene monomer) and PTFE (polytetrafluoroethylene) seats.

Sizing a control valve for liquid flow is one of the most critical responsibilities a process engineer faces. An undersized valve starves the system, causing production bottlenecks, while an oversized valve hunts continuously, wears out its trim prematurely, and leads to costly unplanned shutdowns. ......

Proper placement of a Breather Valve on a fixed-roof storage tank is not a matter of guesswork—it is a critical engineering decision that directly impacts safety, emission control, and operational efficiency. For facilities relying on atmospheric or low-pressure storage, the installation location de......

When engineers face demanding steam systems above 400°C, the valve selection process often becomes a battleground between reliability and cost. The Metal Hard Seal Butterfly Valve has emerged as a serious contender in this space, but does it truly deliver the long-term performance that high-temperat......

​In modern commercial transportation, the air brake system plays a critical role in ensuring vehicle safety and operational reliability. However, compressed air systems often generate moisture, oil residue, and impurities during operation. Without effective drainage, these contaminants may accumulat......
