avst
Type AVST : Through type series couplings, Coupler & Adaptor both halves does not have valve mechanism. This one has a full flow straight through capacity because it is without valves. To disconnect pull the sleeve as well as the adaptor and to connect again pull the sleeve and push the adaptor.

SEAL MATERIAL
Selecting the right seal material depends on which fluid type and temperature range is used listed below. This will greatly influence the life of the couplings. The standard seal material is nitrile rubber.
RUBBER OPERATING TEMPERATURE RECOMMENDED APPLICATION
NITRILE -20°C TO + 90°C OIL RESISTANT
NEOPRENE -20°C TO + 100°C FREON / OZONE RESISTANT
EPDM -20°C TO + 120°C STEAM RESISTANT
SILICON -20°C TO + 180°C DRY HEAT
VITON -20°C TO + 220°C HEAT AND / OR CHEMICAL
TEFLON -40°C TO + 260°C HIGH TEMPERATURE
QUALITY CONTORL
Each AVLOK Coupling manufactured goes through stringent quality control, right from the procurement of raw material upto final stage.
PRECAUTION :
  • Avoid connecting or disconnecting a coupling under pressure.
  • Residual pressure in a coupling may make it difficult to connect. In such a case, do not strike the valve end to depressurize it.
  • Improper selection of seal rubber may cause leakage.
  • Dust or flaws in the seal may cause leakage.
  • Improper selection or improper use of the products can cause personal injury and property damage.
FEATURES :
Operation: The sliding sleeve on the coupler is pulled back, the adaptor is inserted, then the sleeve is pushed forward to make the connection. The seal is made by poppet valves in each component, which close during the disconnection cycle.
