The stainless steel hard seal ball valve features a metal-to-metal seal between the sphere and the valve seat. This sealing structure, which incorporates a flexible spring, overcomes the limitations of soft sealing ball valves, especially at low operating temperatures, and is suitable for media containing granular particles. Designed for high-temperature and high-pressure applications, the stainless steel hard seal ball valve is ideal for use in equipment and pipelines handling water, steam, oil, viscous fluids, and particulate media. Its robust construction ensures reliable performance in demanding environments.
