FAQ's of REGO Stainless Steel Globe Valves for Cryogenic Service SKS Advantage Series Short Stem:
Q: How does the short stem design benefit cryogenic applications in the SKS Advantage Series globe valve?
A: The short stem design reduces heat ingress through the valve, preserving the insulation integrity of cryogenic piping systems and improving energy efficiency. This feature is particularly vital for maintaining stable media temperatures in applications such as liquid oxygen, nitrogen, argon, and carbon dioxide.
Q: What are the standard connection types and can they be customized for specific projects?
A: Standard end connection options include butt weld, socket weld, and female NPT, but they can be customized upon request to accommodate unique piping requirements or retrofit situations. This flexibility allows seamless integration into varied cryogenic systems.
Q: When should the stem packing be adjusted and how is it accomplished?
A: Stem packing can be externally adjusted using the gland, helping maintain leak-tight performance over time. Adjustment is advised if there are signs of leakage or after extended service intervals, ensuring continued compliance with Class VI leakage standards.
Q: Where is the flow direction marked on the SKS Advantage Series globe valve?
A: The flow direction is clearly indicated on the body of the valve, guaranteeing correct installation and optimal operation for unidirectional flow control within cryogenic liquid systems.
Q: What is the process for maintaining or servicing these globe valves?
A: Maintenance is straightforward thanks to the external adjustable gland and user-friendly construction. Regular inspection for packing integrity and periodic cleaning of the polished surfaces ensure long-term reliability and performance in cryogenic conditions.
Q: What are the benefits of using PTFE stem packing and PCTFE sealing in this valve?
A: PTFE stem packing and PCTFE sealing offer exceptional chemical resistance and low friction operation, minimizing leakage and wear. These materials enhance the valve's longevity and reliability when exposed to aggressive cryogenic media.
