Made of die-cast or gravity-cast aluminum alloy, it offers light weight, high strength, corrosion resistance, and is easy to install and maintain. It is particularly suitable for systems that are sensitive to equipment weight.

Top-mounted structure : Reduces the number of valve body connection bolts, enhances overall reliability, effectively counteracts the influence of system weight on valve operation, and improves long-term operational stability.

Composite valve plate design : The butterfly plate uses a carbon steel inner liner and a wear-resistant polymer material (such as nylon 11), combined with a wear-resistant rubber sealing ring, significantly improving wear resistance and extending service life.

II. double sealing

Soft sealing (such as NBR, EPDM rubber): Suitable for normal temperature and low-pressure environments, with excellent sealing performance, achieving zero leakage;

Hard sealing (stainless steel + hard alloy): Suitable for high-temperature and high-pressure or particle-containing medium working conditions, although the sealing performance is slightly lower, it is wear-resistant and has a long service life.

Electric actuator: Supports remote control, automatic adjustment, and intelligent monitoring, can integrate sensors and industrial communication protocols, achieving precise opening control and system interconnection, enhancing automation level.

III. Applicability and Maintenance Convenience Widely applicable conditions:

Nominal diameter can reach DN1000, temperature range covers -29°C to 300°C, pressure rating PN1.0 to 1.6 MPa, suitable for coal chemical, mining, pharmaceutical, cement and other industries.

Anti-dust accumulation design : Valve internal cavity is optimized to reduce material residue and avoid blockage, ensuring smooth powder transportation.

Maintenance convenient : Compact structure, supports online maintenance and sealing component replacement, reduces downtime and operational costs.
