Lugged and wafer type butterfly valves can handle high-temperature vapor applications, but there are some crucial factors to consider to think about:

Temperature Ratings:
Lugged and wafer type butterfly valves are readily available with design attributes and material choices that can hold up against high-temperature heavy steam applications.
The maximum temperature level rating for these shutoffs is often in the series of 400 ° F to 600 ° F, depending on the shutoff building and products utilized.
Shutoff Body and Disc Materials:
For high-temperature heavy steam applications, the valve body and disc are usually made from products with high-temperature resistance, such as stainless steel, Inconel, or various other specialized alloys.
These products can withstand the elevated temperatures and maintain the shutoff's structural honesty and sealing performance.
Seat and Seal Materials:
The seat and seal materials in the valve are important for making certain reliable procedure in high-temperature steam settings.
Typical high-temperature seat and seal materials include PTFE, PEEK, graphite, and specialized elastomers that can hold up against the raised temperature levels without deterioration.
Shutoff Design Factors To Consider:
Hauled and wafer type lugged wafer type butterfly valve  made for high-temperature vapor applications frequently include features like double-offset or triple-offset disc styles, which help maintain regular sealing and reduce the risk of seat damage.
The valve layout may additionally include functions like thermal insulation or energetic cooling systems to safeguard the shutoff components from the extreme temperatures.
Installation and Maintenance:
Appropriate installation and upkeep procedures are vital when using lugged or wafer type butterfly shutoffs in high-temperature heavy steam applications.
This may consist of ensuring appropriate alignment, utilizing appropriate gaskets and sealers, and following recommended maintenance timetables to inspect and change wear-prone parts.
Regulatory and Market Standards:
Certain industries, such as power generation, oil and gas, or chemical handling, might have particular needs or standards for making use of butterfly valves in high-temperature steam applications.
Conformity with these standards is crucial for making sure the shutoff's suitability and safety in the designated application.
By meticulously choosing the suitable materials, layout features, and complying with the suggested setup and maintenance practices, both hauled and wafer type butterfly shutoffs can be effectively used in high-temperature heavy steam applications, giving trusted efficiency and lasting life span.
