They are used as a locking device completely blocking the flow of the working medium on pipelines transporting liquefied gas, hot and cold water, oil products, steam and other slightly aggressive media.
Working environment temperature:
from - 40 to + 200°С – Ф, from minus 20 to + 200 ° С – F1
from - 40 to + 120°С – П, from minus 20 to + 120 ° С – П1.
Tightness of the valves is ensured by pressing the "floating" tube with a chrome-plated surface to the sealing rings made of elastomeric material.
Shutter tightness - according to class A ГОСТ 9544-93.
Accession to the pipeline - flange, (delivery of cranes with counter flanges is possible).
Climatic performance:
- moderate - У1 (ambient temperature)
from minus 40 to + 45 ° С;
from minus 20 to + 45 ° С;
Cranes are made with manual control of ground installation.
Average service life of cranes, years, not less - 12
Production and delivery according to ТУ У 29.1-00217679-027-2004.
Design features:
- low hydraulic resistance;
- absence of "stagnant" zones in the housing;
- ability to install in any position;
- the possibility of replacing the sealing elements.
Reference number when ordering a manually operated flanged ball valve DN50 PN1.6 with working medium temperature - Ф
