FEATURES
Since static pressure of the liquid in the tank acts to increase
the contact pressure on the valve seat, it contributes to tight
shut off.
The valve body made of stainless steels is extremely corrosion
resistant and durable.
The soft seating arrangement can be provided.
The plug/disk can be removed extremely without the valve plug
from the body. This construction permits easy replacement the
valve disk in a short
Time. The shape of the flow passage to discharge an immerse quantity
of liquid from a vessel quickly.
The internal design does not allow discharged liquid to remain
in the valve.
The valve plug so constructed that the liquid is discharged when
the valve stem is moved upwards.
INSTALLATION NOTE
Instead a discharge valve vertically with the hand wheel downwards.
Do not install a valve horizontally as the valve stem may deviate
from the centre line, causing leakage through the valve seat of
the gland packing.
In designing the piping, note that the size of inlet connection
is larger than the body size. Design the installation of a valve
on a tank so that the valve seat and the bottom of the tank will
be on same level.
