Component Specifications

Definition
A specialized industrial component designed to provide controlled venting and pressure equalization in feedwater tank storage sections. It prevents vacuum formation during drainage and allows vapor release during heating cycles while maintaining system integrity.
Working Principle
Operates on differential pressure principles, opening when internal tank pressure exceeds atmospheric pressure by a set threshold or when vacuum conditions develop during fluid withdrawal. Typically incorporates check valve mechanisms or pressure-sensitive diaphragms.
Materials
Stainless steel 316L (ASTM A240), food-grade EPDM or Viton seals, brass or aluminum alloy fittings
Technical Parameters
  • Flow Capacity 10-100 m³/h
  • Vacuum Relief 0.05-0.1 bar
  • Connection Size DN25 to DN100
  • Pressure Rating 0-10 bar
  • Opening Pressure 0.2-0.5 bar
  • Temperature Range -20°C to 150°C
Standards
ISO 5211, DIN 11864, ASME B16.5

Frequently Asked Questions

What is the primary function of a vent connection in feedwater tanks?

To prevent vacuum formation during drainage and allow controlled release of vapors during heating cycles while maintaining system pressure balance.

How often should vent connections be inspected?

Quarterly visual inspections and annual functional testing are recommended, with more frequent checks in high-cycling or corrosive environments.

Can vent connections be used with different media types?

Yes, but material compatibility must be verified - stainless steel for general applications, with specific seal materials for chemical or high-temperature services.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
