Klinger AB Cocks

AB-Cocks are simple constructed, robust shut-off cocks which are specially designed for the measurment engineering. Due to their reliability and economic efficiency they are applied by the million.

Operating Principles

A cylindrical cock plug and an elastic packing sleeve enable a fast opening and closing over a 90° movement. This is ensured by using a stop which is rigidly attached by a circlip (valid for straight way cocks AB). Type MAB cocks for gauge meters have no integrated stop (type MABAL is excepted). The operation is carried out with a removeable handle. All Klinger AB-Cocks are closed by turning clockwise with the exception of types ABIE and MABAL which are closed counterclockwise.

Advantages:

  • 90° operation ensures immediate opening and closing procedure.
  • Generously dimensioned sealing surface which guarantees leak-tightness across the bore and to the atmosphere, hence: no false instrument readings.
  • Hand operation enables throttling, therefore usage in blow-down lines possible.
  • Simple design (only one moving part) ensures high operation safety and long durability.
  • The packing sleeve, the only part which is subjected to wear, can be replaced within minutes with the AB-Cock staying in line.
  • No jamming caused by corrosion.
  • Special designs for applicions with pressure gauges, indicators and liquid level gauges are available.

Fields of Application:
  • Processing industry
  • Automation
  • Shipbuilding industry
  • Diesel engines
  • Compressed-air supply
  • Instrumentation and control
  • Energy generating industry
  • Oil and gas refineries

Important Note Regarding Operating Limits:
Please note that the maximum operating temperature of each KLINGER AB-cock depends on the respective operating pressure as well as on the materials of body or sealing. The pressure and temperature limits are shown in the P-/T-diagrams.
