A bitumen valve is a high-temperature industrial valve designed to control the flow of bitumen, asphalt, and other heavy, viscous hydrocarbons that must be handled while hot.

Bitumen is thick, abrasive, and must be transported at elevated temperatures, so valves require heat-resistant metals, durable seat materials, and designs that prevent clogging or wear.

Most bitumen valves are built for continuous service between 150°C and 250°C, with some designs capable of even higher temperatures depending on materials used.

Stainless steel seat rings provide superior durability, abrasion resistance, and long-term sealing performance under high temperatures and with viscous, particle-laden media.

Double-offset and triple-offset butterfly valves are commonly used because their geometry reduces seat wear, minimises sticking, and handles high temperatures effectively.

Yes. Bitumen solidifies when cooled, so valves are often insulated or equipped with heating jackets, steam tracing, or electric heaters to maintain proper flow.

Using oversized flow paths, smooth internal surfaces, proper heating, and metal-seated designs helps prevent buildup and ensures consistent operation.

Many bitumen valves—especially metal-seated designs—are firesafe certified to maintain essential sealing performance in emergency fire conditions.

They are widely used in asphalt production plants, road-paving facilities, terminals, refineries, tank farms, and heavy-oil processing operations.

Maintenance frequency depends on temperature, flow conditions, and media quality, but metal-seated designs typically require less maintenance than soft-seated alternatives.

Bitumen valves can be fitted with manual gears, electric actuators, pneumatic actuators, or hydraulic actuators, depending on process requirements.

Yes. High-performance double-offset and triple-offset valves are suitable for both reliable isolation and controlled throttling in hot-bitumen service.
