※ Notes:

1) Discharge capacity, qw, is based on index test with rigid-rigid bedding condition and calculated based on qw = Q/i x RT, where Q is the flow rate per each unit of time(m3/s), i is hydraulic gradient and RT is the temperature correction coefficient.
2) The values given are indicative and correspond to average test results obtained in our laboratory and independent authorized institutes.
3) The above information is subject to be revised according to new developments and findings.
4) Various specifications of PVD are available upon customer’s demand.
