Product Focus: 5/8” Fully Bi-directional V1-1 Isolation Valve

v1-1_valve

The ValvTechnologies 5/8” fully bi-directional V1-1 isolation valve is designed to provide 100% zero-leakge for customers in the fossil power and nuclear generation markets. This is the first fully bi-directional, zero-leakage metal seated ball valve on the market.

This 5/8” V1-1 valve prevents the load spring from collapsing, providing tight shutoff or 100% zero-leakage after a reverse flow condition. Most power plant ball valves are uni-directional which makes the valves vulnerable to failure when they are exposed to back-pressure. ValvTechnologies 5/8” bi-directional flow capabilities protects against damage to the internal components and load spring when the valve is exposed to back pressure, guaranteeing Class V shutoff in the reverse direction after an upset condition.

Where is this valve usually found?

  • Super heater attemperation isolation valves
  • Reheater attemperation isolation valves
  • Drum level control valves - high, intermediate and low pressure
  • Main steam block valve - bypass valve application
  • Sight glass isolations
  • De-super heater system isolations

What industries can use the bi-directional V1-1 valve?

  • Fossil power
  • Nuclear power
  • Any industry where customers can benefit from a zero-leakage isolation solution

How do customers benefit?
With the new design, customers will benefit by increased security, less downtime and lower maintenance. During an upset condition, the process flow can be unpredictable, and in most cases, the performance of the equipment that experienced the upset is jeopardized. With the ability to handle pressure in both directions, the valve will remain reliable and low maintenance.

Customers will see a significant reduction in failures on a variety of valves including boiler feed recirculation valves, feedwater heater isolation bypass valves and feedwater isolation bypass block valves.
