We have recently supplied several valves for a new build pumping station for Irrigation Water and Network in the Middle East Area.
On the picture clearly shown our series EVFS- series 13 with a high grade Stainless Steel Duplex disc, EPDM vulcanized, bonded rubber lining and dry shaft design. This material configuration is selected to be very suitable for TSE Water (Treated Sewage Effluent) and comes with our standard 5 years warranty!
Also have a look at the mounting of the valve as an end of line valve. Our valves are typically designed for such application.
