All screwed valves are supplied with Herz 4000 series Metering Stations and the flanged valves are supplied with an orifice plate. Kvs values for these are shown below. Full details of kv values at each valve position are available on request.

To help with larger projects we offer the use of our Flow Computer that will enable you to pre-programme the valves schedule on your PC, download this into the Flow Computer and when all readings have been logged on site, the results are transferred through Microsoft Excel directly into the final report. Regularly calibrated during use, this instrument ensures the figures are as accurate as possible.

Max Temperature 120ºC Pressure Rating PN16
