J-VALVES
Main Features
Two-Piece Structure: The valve body adopts a two-piece design, facilitating installation and maintenance while ensuring the compactness and reliability of the valve.
Full Bore Design: Provides higher flow capacity and lower pressure loss, suitable for working conditions requiring large flow rates.
Low-Temperature Application: Specifically designed for extreme low-temperature environments, with an operating temperature range of -196℃ to 150℃. It is suitable for low-temperature media such as liquefied natural gas (LNG), ethylene, oxygen, and hydrogen.
Stainless Steel Material: The valve body and main components are made of stainless steel (such as 304, 316, etc.), featuring excellent corrosion resistance and high-temperature resistance, applicable to various media.
Flange Connection: Adopts flange connection conforming to international standards such as ASME, DIN, and JIS, with reliable sealing performance and easy integration with pipeline systems.
Fire-Safe Design: Complies with API 607 fire safety standards, ensuring sealing performance is maintained even in extreme situations such as fires.
Anti-Static Design: Prevents static accumulation caused by medium flow, improving safety.
ISO 5211 High Mounting Platform: Conforms to the international standard mounting platform, facilitating direct installation of electric, pneumatic, or manual actuators without additional adapters.
Multiple Operation Methods: Can be equipped with manual, pneumatic, electric, and other actuators to meet different operational needs.
