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.
