Alloy steel gate valve

The Hanno Valve Alloy Steel Gate Valve is developed for industrial systems where valves need to operate under demanding temperature and pressure conditions.

Compared with standard valve materials, alloy steel is commonly selected for high-temperature applications because of its ability to maintain mechanical performance under elevated temperatures. Cr-Mo alloy steel grades, including WC6, WC9 and C5, are widely used in power generation, refinery and other industrial applications where material performance is important.

Material Selection of Alloy Steel Gate Valve

Material selection directly affects valve performance in high-temperature applications.

Alloy steel containing chromium and molybdenum is commonly used for high-temperature valve manufacturing. Chromium helps improve oxidation resistance, while molybdenum contributes to high-temperature strength.

Different material grades are selected according to actual working conditions, including operating temperature, pressure, medium characteristics and project requirements.

WC6, WC9 and C5 Alloy Steel Materials

WC6, WC9 and C5 are commonly used Cr-Mo alloy steel grades for industrial valve applications.

WC6 and WC9 are often selected for high-temperature services, while C5 is used for applications requiring specific material performance under demanding operating conditions.

The final material selection depends on the technical requirements of each project.

Pressure-Seal Bonnet Design for High Pressure Applications

For high-pressure valve systems, sealing structure is an important consideration.

Hanno Valve Alloy Steel Gate Valve can be designed with pressure-seal bonnet structures for Class 900 to Class 2500 applications according to customer requirements.

The pressure-seal bonnet design uses internal system pressure to enhance sealing force between the bonnet and valve body, making it suitable for high-pressure industrial applications.

Hardfaced Seats for Improved Wear Resistance

The seat area plays an important role in valve sealing performance.

Hanno Valve Alloy Steel Gate Valve can be equipped with hardfaced seats according to application requirements. Hardfacing technology helps improve surface wear resistance and supports long-term sealing performance in demanding working environments.

The suitable seat material and configuration can be selected based on the customer's operating conditions and project specifications.
