Product Description

J-VALVES provide Industrial Valves, including ,  and other types , which use for pipeline and equipment connections. 
 
Our Products could produce in both casting and forging type to meet different applications. J-VALVES products could meet standards requirements. 

Product Description

The J-Valves ANSI PN300 F304 Stainless Steel Cryogenic Rising Stem Flanged Gate Valve is a high-performance industrial valve specially developed for extreme low-temperature working conditions. It adopts F304 forged stainless steel as the core material and a rising stem structural design. Its pressure rating complies with the ANSI Class 300 standard (corresponding to PN300), enabling reliable shut-off and control of media in cryogenic environments.
 
Manufactured in strict accordance with international standards such as API 600 and ASME B16.34, this product integrates core advantages including high strength, low-temperature resistance, and zero leakage. It serves as a key control component in cryogenic media transportation systems within fields such as liquefied natural gas (LNG), industrial refrigeration, and petrochemical engineering.
