A family run company founded in 1875, AS Schneider is one of the world-wide leading manufacturers of Instrumentation Valves and Manifolds. The company shapes this branch with technological diversity and many innovations.

The instrumentation products are mainly used for pressure and differential pressure measurement in all ranges of engineering.

Important fields of applications are:

  • Chemical, petrochemical, offshore industry
  • Oil & Gas production & transmission
  • Nuclear power plants
  • Chemical, petrochemical, offshore industry
  • Steel, cement, sugar plants
  • Sea-water desalination plants
  • Fuel gas desulphurization plants
  • Natural gas production and gas transmission industries

AS-Schneider utilizes materials such as steel, stainless steel and brass - exotic alloys such as Monel, Hastelloy, Titanium, and Duplex are also used. The valves and manifolds are manufactured for extreme conditions, they must resist pressures of up to 2000 bar, temperatures up to 600 °C, and very aggressive and highly toxic media, with permissible leak rates of almost zero (10-7 mbar x l/sec).

Quality without compromise

We guarantee for functionality and reliability of our products and processes by an integrated Quality Management System. TÜV SÜD certified AS-Schneider according to ISO 9001:2008.
