1 : Description
The Type KZ03 pressure regulator with air lter lters the supply air and regulates
the output pressure for various pneumatic equipment.
KZ03-1
140 kPa (image with optional gauge)
KZ03-2 for Variable output (Max. 400 kPa)
KZ03-3 for Variable output (Max. 700 kPa)
~Note The number “7” is stamped
with permanent ink on the body
of KZ03-3 to tell apart from
KZ03-2
2 : Operational Principal (Refer to the illustrations on page 2)
The air supply from the primary air intake goes through the lter (15), ltrating
foreign materials. The air keeps owing to the secondary air side until the secondary
pressure balances o with the set spring (15) and shuts o the poppet valve [7]. If the
secondary pressure goes up higher than the set pressure, the diaphragm [6] will rise,
let the extra air escape through the gap between the poppet and the seat ring to the
bleeding hole.
