TECHNICAL SPECIFICATION 3722-014-22955745-2014 Customs union declaration of conformity № RU Д-RU.АЯ41.В.00627

We supply flanged membrane stop valves of cast iron lined with polyethylene or fluoroplast having nominal inside diameter from 15 to 100 mm. They are used as the stopping element in pipelines for liquid and gaseous corrosive media not containing solid particles at pressures of 0.63; 1.0; 1.6 MPa (6.3; 10; 16 kgF/cm2 respectively), depending on the nominal inside diameter and the body lining material, at temperatures ranging from - 15 to + 130 °С. Any installation position of the valves on a pipeline is possible.

Valve 1 – body; 2 – cover; 3 – membrane with screw; 4 – crosshead; 5 – stem; 6 – bushing; 7 – handwheel; 8 – cap nut
