different types of purposes, but mainly they
are used for water works purpose. Our valves
are ISI marked. They are available in two

casting to final testings. These values are
tested hydraulically in accordance with IS

Normally Flanges are
drilled as per IS : 1538 but any type of drillings
like BS : 10, DIN, ASA, etc. can be provided if
so desired. For certain special purposes we have
also designed modified valve like in case of plain
ended jointing valves with plain ends instead of
flanged can be supplied. For certain industrial
use it is required that stem should be rising. In
such cases we have designed valves with rising type
stem or yoke type. |
| For large cities supply
lines we also manufacture Sluice valves of Nominal
Bone sizes 350mm, 400mm & 450mm in Pn 0.6 &
Pn 1.0 which are manufactured as per IS : 2906. |
