Not all valves are created equal, and nowhere is this more apparent than in extreme service applications. High-pressure, high-temperature, and abrasive or corrosive environments demand a valve that is engineered for resilience. Fangyuan's Expanding Gate Valve is purpose-built to excel where others fail, providing reliable performance in the most challenging conditions.

In high-pressure oil and gas production and transmission, the valve's mechanically expanded seal ensures integrity even under severe pressure cycling and water hammer effects. The robust construction and precise machining prevent structural failure, while the dual seals contain the energy of the system safely. For high-temperature services in refineries and power plants, our valves are designed with special materials and clearances to handle thermal expansion without binding or losing seal.

Abrasive slurries in mining or pulp & paper applications are notorious for destroying valve seats. The Fangyuan Expanding Gate Valve’s minimal seat contact during operation is a critical advantage. By avoiding the grinding action of a sliding gate, the seats are shielded from particulate damage, ensuring a long-lasting seal. Furthermore, we offer specialized trim and hard-facing options to combat erosion and corrosion, tailoring the valve to your specific media.

When failure is not an option, you need a valve you can trust. Fangyuan provides that confidence. Our commitment to quality control and rigorous testing means every Expanding Gate Valve that leaves our facility is ready to perform under pressure, heat, and abrasion. Trust your most critical operations to the valve engineered for the extremes.
