FAQ's of REGO Stainless Steel Gate Valve for Cryogenic Service 110 Series:
Q: How does the extended bonnet design benefit cryogenic applications?
A: The extended bonnet design helps insulate the stem and packing area from extreme cold, preventing ice formation and maintaining the integrity of the seal. This ensures reliable operation and safety when handling cryogenic fluids at temperatures as low as -196C.
Q: What standards and certifications does the REGO 110 Series Gate Valve comply with?
A: This valve is manufactured in accordance with ASME B16.34, API 600, and API 598 standards. It is also available with ANSI, DIN, and JIS end connection standards as per request, ensuring compatibility with various international systems and regulatory compliance.
Q: When should I use this gate valve in my process system?
A: This gate valve is ideal for processes requiring tight shut-off and safe control of cryogenic fluids such as LNG, liquid nitrogen, oxygen, argon, and carbon dioxide. It is suitable for both industrial and commercial settings where reliable operation at low temperatures is essential.
Q: Where can the REGO Stainless Steel Gate Valve be installed?
A: It can be installed in facilities that transport, store, or process cryogenic gases and liquids, including petrochemical plants, industrial gas suppliers, and cryogenic storage systems. The valve's connection options and adherence to major standards ensure seamless integration into various pipelines.
Q: What is the process for ensuring a leak-free seal on this valve?
A: The valve undergoes rigorous body and seat testing-1.5 times and 1.1 times the rated working pressure, respectively-to confirm tight shutting and leak-free performance. Its PTFE or metal-to-metal sealing, combined with advanced stem packing, also helps achieve a reliable closure.
Q: How do I operate and maintain the REGO 110 Series Gate Valve?
A: Operation is manual using the robust handwheel. Its outside screw & yoke (OS&Y) and rising stem make position indication and maintenance straightforward. Regular visual inspections and periodic lubrication of moving components ensure optimal performance over time.
Q: What are the key benefits of choosing this cryogenic gate valve for my facility?
A: Key benefits include exceptional insulation performance at cryogenic temperatures, low emissions stem packing, bidirectional or unidirectional flow, secure manual control, and compliance with recognized industry standards. Features like the blowout-proof stem, full bore, and multiple size and connection options offer flexible and reliable operation.
