Product Focus: Sky Vent Valves

sky_vent_valveCutting-Edge Isolation Technology 
To address issues of high-temperature, extreme noise and absolute tight shutoff during initial operation of combined cycle plant start-up, ValvTechnologies introduces sky vent valves. Sky vent valves are designed to address the high-performance demands of steam power generation start-up, ensuring plant piping and equipment do not rise in temperature too quickly protecting it from thermal induced stresses. ValvTechnologies’ sky vent valves relieve pressure during a plant trip or upset condition.

Where is this valve usually found?
Sky vent valves are found in steam power generation applications.


Who purchases sky vent valves?

  • Combined-cycle electrical power generation stations
  • HRSG equipment manufacturers
  • Architect and engineering firms/engineer, procure and construct (EPC/EPCM) contractors

What is special about ValvTechnologies’ sky vent valves?
Sky vent valves are installed in the highest-cost energy systems in the plant. If this valve does not isolate fully, high-cost energy passes directly to the atmosphere, decreasing plant efficiency during all hours of plant operation. The ability to isolate with zero-leakage is critical in this application and ValvTechnologies’ sky vents are uniquely suited to meet this requirement.

Due to enormous pressure drops, extreme noise is an issue. The ValvTechnologies’ sky vent design provides a less torturous flow path than competing globe valve designs, mitigating noise abatement issues.

ValvTechnologies’ sky vent design features offer higher capacities (Cv) than competing globe valve designs of the same nominal size, allowing ValvTechnologies to offer a customer savings in piping and valve costs.
