Air poppet valve VAN

  • Improved from the VA base, the inner core is an inner hexagonal structure, to avoid the uneven ejection section caused by rotation.
  • Added spacers with a filter screen to filter out impurities in the airway and facilitate installation

Combining the advantages of CUMSA’s FV and CUMSA’s VH,we specially made filter gasket can not only filter debris and impurities in the airway, prevent the spring from getting stuck by debris and impurities, but also make it easy to remove the air valve without damage
When the air ejector is matched with the shell at60 degree inclination,the extrusion separation decreases and no stuck.
Core and shell are rotated by hexagonal, and arc surface with 5 degree deviation is allowed to be used.(Refer toP 1)
Conical surface acts as both supporting and matching surface,so the sealing is more precise.
Adding a filler for removal, the bottom of the gasket can be knocked out without cracking. More importantly, the gasket is equipped with a filter, which filters out impurities in the airway to prevent the Air Poppet valve AJV from entering foreign bodies and failing.
