General information

  • Valves have are fully welded or bolted (Split body).
  • Full-bore design.
  • They have flanged or weld-in connections.
  • Available sizes: DN6 ÷ DN700.
  • Pressure range: PN16 ÷ PN420 (ANSI 150 ÷ 2500).
  • Temperature range: -30 ÷ + 60°C (special designs on request).
  • Medium: natural gas (special designs also possible).
  • With the trunnion ball or floating one.
  • SOFT or PMSS seal.
  • Systems:
    • emergency sealing (for selected diameters)
    • SPE (single piston) or DPE (double piston)
    • drainage and venting
    • gradual pressure equalisation so-called by-pass
  • Fire safe-resistant and anti-static design(for selected diameters).

Corrosion protection coatings

  • As a standard, the ball valves in the above-ground version are protected by spray painting using electrostatic technology, depending on the corrosivity category in class C4 or C5 according to EN ISO 12944-2.
  • The underground components of the tap can be PUR-coated and tested in accordance with EN10290.

Special designs

  • Special designs for temperature ranges on request.
  • Special corrosion protection coatings according to customer specifications are possible.
  • On request, we manufacture ball valves in special designs and materials, e.g. stainless steel or NACE-certified material MR0175.
  • We also manufacture valves, taking into account specific customer requirements, such as final pressure and functional testing of taps or checking the quality of anti-corrosion coatings.
