Description

The CRYOGENIC THREADED GATE VALVE TYPE 01355 is engineered for superior performance in extreme low-temperature environments, making it an essential component for industries such as LNG processing, cryogenic storage, and aerospace applications. Constructed with high-grade materials resistant to thermal contraction and embrittlement, this valve ensures reliable shut-off and flow control where temperatures plummet below -150°C. Its threaded connection design facilitates easy installation and maintenance, reducing downtime in critical operations.Key features include:Robust body crafted from stainless steel or specialized alloys to withstand cryogenic conditionsBidirectional sealing capability for enhanced safety and leak preventionThreaded ends (NPT or BSP) for secure, pressure-tight connections without weldingCompact and lightweight design, ideal for space-constrained installationsCompliance with international standards like ISO 28921 and ASME B16.34This valve is designed for manual operation, providing precise control over fluid flow in systems handling liquefied gases such as nitrogen, oxygen, argon, or helium. Its gate mechanism offers minimal pressure drop when fully open, optimizing energy efficiency in piping systems. Regular maintenance is straightforward due to its accessible internal components, ensuring long service life even under cyclic thermal stresses.Ideal for use in cryogenic transfer lines, vacuum jackets, and cold boxes, the TYPE 01355 valve undergoes rigorous testing—including helium leak tests and cryogenic cycling—to guarantee performance integrity. Partner with confidence for applications demanding durability, safety, and efficiency in sub-zero environments.
