single-double-block01

Hawa Valves can meet all the requirements coming from the Customer, including the need of valves with reduced dimensions and weight. For Double Block and Bleed design, Trunnion or Floating Type, special body design without flanges results in a very short end-to-end dimension. Pipeline bolts shall be screwed into threaded blind holes machined into valve body. This customization of the product is possible, indeed, on all dimensions coming from international codes (valve bore, valve end to end) of coming from Hawa’s standard production range (valve weight, height from ground, operator height form line axis) can be modified trying to meet the requirements of the Customer for the specific project.
