Engineered for applications like LPG and ammonia where standard carbon steel fails, guaranteeing safety against brittle fracture.
Standard carbon steel (A216 WCB) becomes dangerously brittle below -29°C. For critical applications down to -46°C, we mandate the use of superior materials like ASTM A352 LCC/LCB or Austenitic Stainless Steel (CF8/CF8M). These alloys are specifically designed with enhanced nickel content and grain structures that maintain excellent impact toughness at low temperatures, providing an essential layer of safety and preventing catastrophic failure.
"Our previous carbon steel valves on the -42°C LPG lines were a constant source of anxiety... JRVAL's LCC-body lug valves gave us the safety margin we needed. They passed ultrasonic tests with flying colors after two brutal winters, completely eliminating the risk of brittle fracture."— Chief Safety Officer, North American LPG Distribution Discover the Science of Low-Temp Steel →

Offers the most secure and robust connection for higher-pressure low-temp media, ensuring absolute joint integrity.
Learn MoreCost-effective and reliable valve solutions for ethylene, ethane, and other industrial gases using specially modified materials.
For services down to -101°C, we offer a unique, cost-effective solution built on specially modified carbon and stainless steels. Through a proprietary multi-stage thermal treatment process, we refine the material's microstructure, enhancing its low-temperature ductility and impact strength far beyond standard specifications. This innovative approach delivers the cryogenic performance required for applications like ethylene processing, without the higher cost of specialized alloys.
"We were skeptical about using modified carbon steel for our -100°C ethylene cracking unit... Three years in, these valves are performing flawlessly, with zero leaks or operational issues. They delivered on their promise of cryogenic performance at a better price point."— Plant Manager, Gulf Coast Petrochemicals Explore Our Material Modification Process →

The premier choice for critical services like ethylene, offering bi-directional zero-leakage with a durable metal seal.
Learn MoreThe ultimate solution designed for ultra-low temperature media such as Liquefied Natural Gas (LNG), liquid nitrogen, and liquid hydrogen.
At the extreme temperature of -196°C, only austenitic stainless steels (like CF8/CF8M) retain the essential ductility to operate safely. Our deep cryogenic valves feature full austenitic stainless steel construction combined with the critical "Extended Bonnet" design. This component physically isolates the stem packing and actuator from the cryogenic fluid, preventing packing freeze-up and actuator damage, ensuring long-term, reliable zero-leakage performance.
"When handling LNG at -162°C, our previous valves were failing due to stem icing... JRVAL's extended bonnet triple-offset valve completely solved this. Its design keeps the actuator area above 0°C, ensuring total operational safety and reliability."— Equipment Manager, TEPCO (Tokyo Electric Power Company) Understand the Principles of LNG Valve Design →
The ultimate choice for LNG, Air Separation Units (ASU), and applications demanding bi-directional zero-leakage and maximum reliability.
Learn MoreOur commitment to safety is absolute. Every low-temperature and cryogenic valve we produce is subject to rigorous testing and adheres to the highest international standards.
Designed and manufactured in strict accordance with cryogenic standards like BS 6364 and ISO 28921-1 for guaranteed safety.
Every heat of low-temp material undergoes Charpy V-Notch impact testing to verify its toughness at the specified minimum temperature.
Valves undergo stringent Helium Mass Spectrometer Leak Detection to ensure bubble-tight, zero-leakage performance under cryogenic conditions.
We provide complete Material Test Reports (MTR) for all pressure-containing components.
We don't only sell generic valves. We provide engineered solutions tailored to the specific operating environment of your process area.
