J-VALVES
Structural Features
Bellows Seal: Uses long-life bellows (e.g., 321 stainless steel, Inconel, etc.) to provide excellent sealing performance and prevent medium leakage. It is particularly suitable for controlling toxic, harmful, flammable, or explosive media.
Non-Rotating Stem: The stem is designed to be non-rotating, which prevents torsion of the bellows and extends the bellows’ service life.
Dual Seal: Equipped with a dual seal system, including bellows and graphite packing, to ensure sealing performance in high-pressure and high-temperature environments.
Welded Seat: The seat is made of welded cemented carbide (e.g., Stellite 6), offering excellent wear resistance and long service life.
Flange Connection: Adopts a standard flange connection method compliant with the ASME B16.5 standard, ensuring reliable installation and sealing performance.
Compact Design: With a small volume and light weight, it is easy to install and integrate into existing systems, saving space.
Multiple Operation Modes: Can be equipped with manual, pneumatic, electric, or hydraulic actuators to realize remote automated control.
