quick connect coupling avdv
Type AVDV : Double valve series couplings, both halves female threaded having valves which operate on the opposed poppet valve principle, valve consists of a spring loaded seat seal with attached valve. A quick pull on the sleeve and the assembly is disconnected, pull again, push the adaptor in coupler half and the unit is connected.
Double valve self sealing couplings seal off at both ends when disconnected is not completely dry, a few CCS of fluid being spilled.
PRECAUTION : Can not be connected / disconnected under pressure.

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.
