High-temperature valves are designed to perform reliably under extreme temperatures and pressures, making them ideal for demanding industrial applications. Available in series valves and ball valves configurations, these valves feature a robust metal seated design that ensures tight sealing and long service life even at high temperature and high pressure conditions. With a wide temperature range, high-temperature valves provide precise control and durability, making them essential temperature valves for systems that require consistent performance under challenging operational conditions.
Valves designed for media temperatures above 425℃ are defined as high-temperature valves and can be of any conventional valve type. They are generally classified as follows:
PⅠ: temperature between 425℃ and 550℃;
PⅡ: temperature between 550℃ and 650℃;
PⅢ: temperature between 650℃ and 730℃;
PⅣ: temperature between 730℃ and 816℃;
PⅤ: temperature above 816℃.
Size:
NPS1/2~~NPS24 (DN15~~DN600); production beyond this range can be customized according to customer requirements.
Material:
Body material per customer order, both cast and forged are applicable.
Internal Parts/Stem:
Configured according to body material or as per customer requirements.
Structure:
PⅠ and PⅡ can use conventional structures with suitable high-temperature resistant materials;PⅢ and PⅣ can use conventional structures with high-temperature resistant low-alloy steel or high-carbon austenitic stainless steel, combined with high-temperature resistant packing and gaskets to ensure valve sealing. Additional measures such as extended valve covers, cooling fins, or middle joint welding can be applied to reduce the temperature at the stem seal area and minimize leakage risk;PⅤ level exceeds the normal temperature limits of metal materials and must use special structures to guarantee valve performance, such as adding thermal insulation materials or designing water-cooling circulation systems.
Operation Mode:
Manual, gear drive, electric, pneumatic, or automatic, etc.
