Ceramic Hemispherical Valve

Description

Ceramic hemispherical valve combines ceramic lining and is a high-performance valve with high wear and corrosion designed and manufactured for your conveying system containing granular media such as powder, slurry, coal powder, dry ash, limestone slurry, catalyst, etc.

The ceramic hemispherical valve provided by TOT is designed for reliability and is widely used in desulfurization systems in power plants, mineral processing pipelines, and general fluid control pipelines in the chemical industry. If you are not using it in an extremely corrosive environment, its durability and sealing performance are something you don’t need to consider too much.

As a professional valve manufacturer with years of export experience, we deliver not only a product—but a long-term solution tailored for industrial challenges. Whether you’re replacing metal-seated valves that wear out too quickly or looking for a more stable long-life valve, our ceramic hemispherical valve will exceed expectations.

Executive Standards

Note: After passing the valve experiment, it is necessary to eliminate accumulated water in the cavity, dry the inner cavity with air, apply anti-rust oil, and block both ends of the diameter with caps.

Designed for Demanding Applications

What sets this valve apart isn’t just the ceramic lining—it’s the engineering behind every detail:

– High-Hardness Zirconia Ceramic Trim: The sealing surface and flow path are protected with precisely machined zirconia (ZrO₂) ceramic components, offering exceptional wear resistance, oxidation resistance, and extended service life.

– API 6D-Compliant Design & Testing: Fully designed and tested in accordance with API 6D, ensuring international standards for dimension, pressure performance, sealing integrity, and material selection.

– Full-Bore, Non-Clogging Eccentric Design: The hemispherical shut-off element rotates on an eccentric axis, minimizing friction during operation. This design allows for full-bore flow and eliminates jamming caused by sediment or solids—ideal for slurry and particulate-heavy media.

– Reinforced Valve Body: The valve housing is cast with wall thickness exceeding standard requirements, enhancing structural reliability and longevity even under cyclic loading conditions.

– Precision-Ground Sealing Surface: The ceramic-to-ceramic sealing interface is meticulously polished for tight shut-off, minimizing leakage and wear over long-term use.
