SCI Air Valves with Resilient Orifices

SCI AIR VALVES have been especially designed to allow the most efficient method of releasing
or admitting air during the filling and emptying pipelines or vessels and the release of air
accumulating in pipeline during normal working conditions.

Features

  • Resilient orifices - Seal from very low to high working pressure ( 0.1-25.0 bar )
  • ABS float - Proven long lasting material. Specific gravity ( 0.75-0.80 ).
  • No protruding levers - This features reduce maintenance and servicing to a minimum.
  • No premature closing.
  • Standard - Comply with JIS B 2063

Small Orifice

{gallery}air_valves/single_small_orif{/gallery}
Automatically releases accumulated air in pipeline.

Large Orifice

{gallery}air_valves/single_lrg_orif{/gallery}
Automatically releases or admits large volume of air for efficient filling or emptying of pipelines
to protect against vacuum or pipeline damage.

Double Orifice & High Speed (Quick Type)

The combination of small and large orifice becomes a single unit.

Double Orifice with Integral Isolating Valve

{gallery}air_valves/double_orif_int{/gallery}
The combination of small and large orifice plus integral isolating valve becomes a single unit.
