High Temperature Resistant Rotary Valve

High temperature resistant rotary valve is designed for extreme working conditions above 260℃, and breaks through the high temperature bottleneck through three core technologies: 310S stainless steel, 304 stainless steel, 316L stainless steel, etc. can be used in materials, graphite composite seal, and the temperature resistance reaches 500℃; water cooling can also be added to ensure the normal use of the equipment.
The customized high temperature resistant rotary valve is a key equipment designed for high temperature conveying environment, and is widely used in high temperature working conditions such as drying system, incinerator ash discharge, kiln feeding, boiler exhaust dust removal, high temperature powder conveying, etc. The design of this equipment breaks the technical bottlenecks of conventional rotary valves such as easy deformation, sealing failure, and unstable operation at high temperature, ensuring stable, safe and continuous operation in extreme temperature environments of 260℃ or even above 500℃.

High-performance heat-resistant material selection
The valve body and rotor parts can be made of high-quality high-temperature resistant stainless steel materials according to the customer's working conditions:
·310S stainless steel: strong oxidation resistance;
·304 stainless steel: strong versatility, suitable for medium and high temperature material transportation;
·316L stainless steel: has good corrosion resistance, suitable for high temperature acid and alkaline working conditions.
·According to the material characteristics and gas composition, material compounding or lining design can be further carried out to ensure long-term operation without deformation and corrosion.
Graphite composite sealing system
·The special graphite composite sealing structure can withstand high temperatures up to 500℃ and has good wear resistance and aging resistance. While ensuring sealing, this sealing structure allows a certain amount of thermal expansion to avoid jamming and leakage, which is an ideal choice for high-temperature continuous working environments.
Optional water cooling system
·For working conditions with large temperature fluctuations or local overheating, the equipment can be customized with a water-cooled jacket or shaft cooling system to control the temperature of key parts through circulating ·cooling water to prevent overheating and failure of bearings and seals and extend the service life of the equipment.
