• When the pressure inside the bowl
is released:
When pressure is released from the bowl q,
piston u is lowered by spring y.
The sealing action of seal !0 is interrupted,
and the outside air flows inside the bowl q,
through housing hole o and drain cock !1 .
Therefore, if there is an accumulation of con-
densate in the bowl q, it will drain out through
the drain cock.
bowl:
When the pressure exceeds 0.1MPa, the force
of piston u surpasses the force of spring y,
and the piston goes up.
This pushes seal !0 up so that the it creates a
seal and the inside of the bowl q, is shut off
from the outside air.
If there is no accumulation of condensate in
the bowl q, at this time float w will be pulled
down by its own weight, causing valve r,
which is connected to lever e, to seal valve
seat t.
condensate in the bowl:
Float w rises due to its own buoyancy and
pushes open the seal created by the valve
seat, t.
This allows the pressure inside the bowl q, to
enter the chamber i. The result is that the
combined pressure inside chamber i and the
force of the spring y, lower the piston u.
This causes the sealing action of seal !0 to be
interrupted, and the accumulated condensate
in the bowl q, drains out through the drain
cock !1 .
Turning drain cock !1 manually counterclock-
wise lowers piston u, which pushes open the
seal created by seal !0 , thus allowing the con-
densate to drain out.

• When there is an accumulation of
• When pressure is applied inside the
• When the pressure inside the bowl is
released:
Even when pressure inside the bowl q, is re-
leased, spring y keeps piston u in its upward
position.
This keeps the seal created by the seal !0 , in
place, thus shutting the outside air from inside
the bowl q.
Therefore, even if there should be some conden-
sate accumulation inside the bowl q, it will not
drain out.
bowl:
Even when pressure is applied inside the bowl
q, the combined force of spring y and the pres-
sure inside the bowl q, keeps piston u in its
upward position.
This maintains the seal created by the seal !0 , in
place, thus shutting the outside air from inside
the bowl q.
If there is no accumulation of condensate in the
bowl q, at this time float w will be pulled down
by its own weight, causing valve r, which is
connected to lever e, to seal valve seat t.
condensate in the bowl:
Float w rises due to its own buoyancy and push-
es open the seal created by the valve seat t.
Pressure passes from the bowl to chamber i.
The result is that the pressure inside chamber i
surpasses the force of the spring y, and pushes
piston u downwards.
This causes the sealing action of seal !0 to be
interrupted and the accumulated condensate in
the bowl q, drains out through the drain cock
!1 .
Turning drain cock !1 manually counterclock-
wise lowers piston u, which pushes open the
seal created by seal !0 , thus allowing the con-
densate to drain out.

• When the pressure inside the bowl is
• When the drain is accumulated in the
• When pressure is applied inside the
released:
Even when pressure inside the bowl q, is
released, the weight of the float w causes valve
r, which is connected to lever e, to seal valve
seat t. As a result, the inside of the bowl q, is
shut off from the outside air.
Therefore, even if there is an accumulation of
condensate in the bowl q, it will not drain out.
bowl:
Even when pressure is applied inside the bowl
q, the weight of the float w, and the differential
pressure that is applied to valve r cause valve
r to seal valve seat t, and the outside air is
shut off from the inside of the bowl q.
bowl:
Float w rises due to its own buoyancy and the
seal at valve seat t is interrupted.
The condensate inside the bowl q drains out
through the knob, y.
Turning knob y manually counterclockwise
lowers it and causes the sealing action of valve
seat t to be interrupted, thus allowing the
condensate to drain out.
