For liquids, gases and steam in hydraulic, pneumatic, heating and steam systems, chemical and food industries application.

These valves are fully constructed from laminated bars. They can, upon request, be manufactured in other types of materials, for use in special working conditions (high temperatures, fluids, etc.). These valves have PTFE (Teflon) packing and Stainless Steel hand wheels or handles (DIN-1.4401) (AISI-316).

Specifications

  • Mobile or floating closure.
  • Reduced pitch.
  • Light tightening of the hand wheel ensures perfect closure, exceeding DIN-3230 standard.
  • Axis with rear closure “back seating” allows the packing to be changed whilst the valve is in use, without any contact with the application medium.
