SHUT-OFF ADJUSTABLE APPARATUS FOR LIQUIDS AND GASES

JOINT COUPLING

Purpose: connection and disconnection of gas communications (pipelines) under overpressure of operating medium without its loss in the atmosphere and pollution of inner cavities with the ambient air.

  

Operating medium: non-aggressive gases, chladones refrigerants.

Notes:

  • specified life (connection-disconnection) - 200 cycles;
  • operating temperature range is from -50 to +50 °; 

 

Using of joint couplings is especially important for ecologically dangerous and aggressive medium as well as for change of short-life units.
